For example, they could be by keeping away from their fare and bringing in to them. US and China could some way or another seek after an all the more yet harsh methodology. This can be through the help of the United Nations to create strategies to be embraced by these nations and if conceivable change the administration through reasonable and straightforward political decision led by United Nations. This can begin with strategy and two-sided exchange among them. The central foundation of the creation of fanaticism and even infringement of human rights by different administration lies in a culture of abusive political rejection, included with strict dogmatism, changing the political culture especially by the United States would include laying radical changes and gazing the nation to a law based culture that again would mean difference in initiative regardless of whether it implies utilization of military by help of United Nation Security Council. Change of administration in a large number of such nations is seen as a rule as another day break particularly through a reasonable law based procedure (Song,

On Tortillas and Community

On Tortillas and Community Hello! One of the first things I wrote about as a staff blogger was my transition from pueblerina to big city girl. A year and a half has passed since that blog post and I’d like to give you an update. When I last checked in, I was just settling into my new life in Cambridge, MA. As a proud, first generation, Mexican-American woman, I found that there were a couple of things that I needed to ensure my happiness, sense of belonging, and community. I had already found the perfect coffee-shop, but there were still a couple of things missing from my list. Ahem: Tortillas. These round slices of heaven are revered in Mexican cuisine; for instance, a tortilla can either make or break a meal: corn tortillas bring out the flavors in tacos al pastor or enchiladas, while flour tortillas are better suited for burritos or just eating them by themselves with a bit of butter. With this in mind, I set out to find a tortilleria or in the very least, good quality tortillas in a super market. Not only did I not find a tortilleria, but I didn’t even find good quality tortillas in the supermarket. Y ahora, que sera de mi? One day a student told me how her mom regularly ships her treats from California and I thought to myself, “Well that’s something, ain’t it?” I quickly called my parents and two days later, I had two packages of freshly made tortillas from the local tortilleria and a package of my favorite chorizo. All of these seemingly small things: tortillas, chorizo, coffee, all of these things can make a person feel at home. But acquiring a sense of happiness, sense of belonging and community requires more than just material things, as cliché as that may sound. The interaction with people from my community is very important to me, as well, to be able to share and bond through stories of common experiences, such as attending quinceañeras, eating tamales, or being the first in your family to go to college. Sigue leyendo. The other day, I was having ice cream with a student I “mentor” (I really think it’s the other way around) and she was telling me she would be pulling an all-nighter studying for her neuroscience class and in the next breath, telling me she would be visiting her abuelita for Christmas break. As she was talking, I couldn’t help but feel so incredibly proud of her for having the fortaleza and coraje to leave her family behind and forge her own path at MIT. This, my friends, this is what makes Cambridge, MA feel like home to me, even if my parents have to send tortillas and chorizo via express mail.

Conservation of Energy Lab Essay - 1536 Words

FREE FALL AND CONSERVATION OF MECHANICAL ENERGY ABSTRACT Free fall is defined as the ideal falling motion of an object that is subject only to the earth’s gravitational field. To prove the law of conservation of energy, the free fall motion of an object can be represented through 3 different analyses; position of the object vs. time, velocity of the object vs. time, and acceleration of the object vs. time. It is observed in this ball toss experiment, at any point during the free fall period, the system contains the same total amount of mechanical energy. This amount is the sum of kinetic and gravitational potential energy.

How to Write Ethos

How to Write Ethos While working on ethos, you have to realize that it has to show the way the readers recognize the writer. Below we present the main features that the readers may find out about the writer. Note, that in the case with ethos the writer never mentions himself. So, among the features the readers may ascribe to you there are lazy, careful, educated, enthusiastic, dishonest, boring, etc. All these features may be ascribed by the reader to the writer after he says what he has to say and the way he says it. Readers have also an opportunity to describe the writer’s appearance, his gender, his fashion style and whether he speaks with an accent. It is highly important for you to set 2 specific aims to reach while building up your ethos. The first one lies in the fact that you have to make your readers trust you. The second – you need to make your readers respect or even like you. When you read â€Å"like you†, don’t think that it is necessary to make your readers go out with you for a date after they finish reading your paper. The point is that readers usually appreciate what you have done, that is they respect you for the interesting paper you have written. In order to create a strong ethos, follow these simple recommendations: You need to have good pathos/logos. You need to show your readers that you have performed a thorough research of your topic. You need to show your enthusiasm concerning your topic. You need to express empathy if it’s appropriate. Remember, in case you perform limited research for your ethos, your readers will definitely be less inclined to trust what you have written. Thus, your support of arguments won’t be convincing and valuable. Never forget to check your paper for grammar mistakes and typos. Otherwise, your readers will never respect you and won’t be interested in reading it at all. Show your readers that you care about what you are writing and be sensitive where it is appropriate.

Media Law in South Africa Free Essays

The Press Freedom Commission (PFC) was launched in July 2011 by the press industry representative body, Print Media South Africa and the South African National Editors Forum in order to set up a suitable regulatory media system for South Africa (Press Freedom Commission, 2012: 1). The Press Freedom Commission that was held earlier this year assessed all measures concerning co-regulation, self-regulation, independent regulation and state regulation so as to ensure that the media is accountable to the public that they serve and similarly to ensure the protection of press freedom (Press Freedom Commission, 2012: 1). This year, the PFC recommended that an independent co-regulatory system , which does not include State participation, would best suit the country. We will write a custom essay sample on Media Law in South Africa or any similar topic only for you Order Now This would mean that the press are accountable to serve in interest of the population (Press Freedom Commission, 2012: 1). With reference to Julie Reid’s and Julie Posetti’s article in the Rhodes Journalism Review, I aim to evaluate various contexts and henceforth provide reasons for why I am in accordance with the co-regulation of the media. Under the South African Constitution, in the Bill of Rights (1996) it is stated that every person has a right to freedom of expression, which includes freedom of press and the media, the freedom to receive or impart information or ideas, freedom of artistic creativity, academic freedom and freedom of scientific research (Act no. : 108 of 1996). Henceforth press freedom means the autonomy to communicate ideas, opinions and information without restraint. The media are a public trust with the ability to inform and influence and because of this power they should serve to represent the interests of the citizens without external institutional constraints. When analyzing freedom of the press with the current regulatory system, there are two powerful institutions in society which cannot be ignored, that is political and economic power. Under apartheid the freedom of the press was heavily restricted. The Newspapers Registration and Imprint Act of 1985, required that all newspapers had to be registered and conform to a strict code of conduct. In addition newspapers were also required to lodge R40 000 as a deposit before they could publish, as a result the act silenced many liberal newspapers (Manoim, 1996: 7). With the transition into a new democracy, self-regulation of the media was employed to uphold freedom of expression, a pivotal component of a true democracy. Self-regulation is a system that operates on self imposed rules by the media, it consists only of representatives of the media profession who use the Journalistic Codes and Ethics as a guideline (Reid, 2012: 1). The relationship between the government/ state and the media is one of conflict and dependency because on the one hand, the media are commonly referred to as the ‘unofficial opposition’ to the government. As ‘watchdogs’ they make public a range of issues concerning health care, education, corruption, unemployment etc and because of these disclosures the government repeatedly attempt to censor their biggest critic. As such, the government proposed a Media Tribunal, which could lead to the forced registration of all newspapers, the registration of all journalists and punitive fines(Reid, 2012: 1). The tribunal exemplifies the government’s hostility towards the media and it clearly epitomizes the Newspapers Registration and Imprint Act of 1985 . Another example constitutes as the Protection of Information Bill which will allow the government to classify specific information which is deemed harmful to the â€Å"national interest†. The government have suggested media-unfriendly laws which pose a threat to attack the heart of the struggle for democracy (Reid, 2012: 1). On the other hand, however, the media are dependent on the government for information and official materials and similarly the government depends on the media to produce important information to their citizens. It is evident that the media plays a large role in making public the successes and the failures of the government, however, I argue that a change in the regulatory system could improve the relationship between the two so that the media do not have their own agendas for the information they produce, but they produce that which of interest of the public that they serve. Although self-regulation of the press was once highly valued, examples like the Murdoch scandal have shown that the system is weak and does not assure the accountability of the press. Journalists from the News of the World were accused of phone hacking, police bribery and using unethical means to obtain ‘public interest’ stories (Posetti, 2012: 19). The self-regulatory system allows for journalists to operate freely without state interference and although there haven’t been any situations like the aforementioned unethical proceedings in South Africa, the regulatory system does not fulfill the democratic vitality of the inclusion of wider population (Reid, 2012: 18). For many years under the rapacious system of apartheid, the black population was silenced, their grievances and njustices undocumented. In this new democracy, the media are still seen to cater for the interests of the elite, this can be conceptualized in Noam Chomsky and Edward. S. Herman’s â€Å"propaganda model†. Granted the media does deliver information to serve the interests of its citizens, news coverage is frequently tailored to what suits the corporate. The med ia are a profit-seeking institution, funded by advertisers and are (sometimes) owned by private investors, this can henceforth lead to the media placing profit above public interest (Manoim, 1996: 4). An example of this can be seen in various newspapers during the apartheid era, particularly the Business Day. The Business Day embraced a conservative liberal take on the apartheid system. The reporting that the Business Day encompassed relied on keeping an apolitical stance and avoided negative consequences of full disclosure. The newspaper did not report on any issues negative aspects of the apartheid system or its effects on the population and the reason for this was to gain more revenue than to possibly create controversy (Manoim, 1996: 4). Another example of this was the recent Marikana shootings, wherein the first pieces of information distributed by the media through print and broadcast, told a story of a violent, armed and angry mob, charging towards apprehensive policemen who then shot the mobsters from afar, in fear of their lives (Johnson, 2012: 1). At least 36 miners were shot dead and because of the inadequate coverage by the media, many people were under the impression that the police action was proportional to the threat posed by the miners. It wasn’t until Greg Marinovich went on to publish shocking findings about the deaths of the Marikana minors, in his article â€Å"The murder fields of Marikana: The cold murder fields of Marikana† (Marinovich, 2012: 1). The article made public that some of the miners had been shot by close range (execution style) and others crushed by police vehicles, thus providing proof that the police did not act in fear, but instead hand the upper hand and viciously killed the miners. In many of the articles published, before Marinovich’s, statements were mainly one sided, comprised of policemen, the mining management and government official (Manoim, 1996: 7). It can be understood that many journalists and news firms did not accurately report on the Marikana shootings because they did not want to cause controversy and did not want to lose revenue. With regards to the aforementioned relationships between the media and political/ economic institutions within the self-regulatory system, I argue that the system is clearly weak. There is indeed more freedom of speech with this system, however, the press aren’t held accountable to the citizens that they serve, the press can be seen to accommodate only the elites and silence the people. For these reasons and the above examples, in my opinion it is clear that the self-regulatory system in inadequate for a new democracy such as ours. The proposed system of independent co-regulation without state or government intervention will best serve the freedom of the press in our country. The system will consist of members of the public (e. g: academics, civil society organizations etc. ) and members of the press industry therefore sufficiently creating integration between the press and the society that it serves (Reid, 2012: 18). The independent system as well as journalists will henceforth be accountable to the public. The co-regulatory system will allow regulatory rules to be created by more than one stakeholder and it will have independence from industries (Press Freedom Commission, 2012: 1). The system should sufficiently allow members of the public and the press to engage with reports made by the independent body. This nature of transparency will build a close relationship between the public and the media and henceforth it will encourage the media to be accountable to the citizens that it serves (Reid, 2012: 18). I believe that the increased integration between the public and the press will give the once unheard voices of the public a platform for their opinions furthermore it will directly assist the country on the road to true democracy. The PFC suggests that the system will introduce a more efficient framework for dealing with sensitive matters especially when dealing with children. There will also be a be a method of â€Å"space fines† which will consist of monetary fines, summons or rulings for any offences made by the press (Press Freedom Commission, 2012: 1). The co-regulatory system proposed by the Press Freedom Commission is not an attack at the freedom of the press, rather, it is very necessary to strengthen the system of the press in South Africa. Co-regulation will not only serve the public because of the system’s transparency and allowance for integration but it could also improve the quality and credibility of journalism in the country. The marginalized and excluded persons of this country need an environment where they are able to make public their discrepancies and regarding the extensive reception to the current self-regulation it is evident there needs to be a change in the system. In my opinion co-regulation will ensure the greatest independence from different influential institutions, it will reinforce the accountability the press should have for the citizens, it will allow for press freedom and furthermore it will assist to uphold the principles of a democracy.

The Workings and Structure of the Heart Essay Example For Students

The Workings and Structure of the Heart Essay IntroductionFor homeostasis to remain balanced throughout the body millions of respiring cells need to discard carbon dioxide and waste products and also replenish with oxygen and nutrients. For this transaction to occur a complex transportation network called the cardiovascular system initiates. The cardiovascular system consists of the heart, arteries and veins. The heart is a double pumping organ which is the driving force of the cardiovascular system, although only weighing approximately three hundred grams the heart is powerful enough to beat over seventy times a minute pumping blood around the body. The heart is located on the left hand side of the diaphragm lying within the mediastinum in the thoracic cavity. Resembling a pyramid on an oblique angle the heart is hollow and composed of three layers, myocardium, endocardium and pericardium. Myocardium formulates the majority of the heart; this is composed of specialised cardiac muscle occurring only in the heart. Endocardium is a smooth delicate membrane, which lines the interior surface of the heart chambers and valves, and the pericardium; which is a connective tissue, this acts as a protective barrier, the fibrous pericardium fuses with arteries which pass through it to form attachments which help to anchor the heart to its surrounding structures The interior of the heart is divided into two sides the right and left, nearly mirror image of each other a few differences can be recorded (see conclusion).Figure 1As figure 1 shows there is a complex network of arteries and veins which branch into the heart. It is through these arteries and veins that blood is transported throughout the body. The arteries carry oxygenated blood from the heart to tissues and cells throughout the body whereas the veins carry deoxygenated blood received to the heart. We will write a custom essay on The Workings and Structure of the Heart specifically for you for only $16.38 $13.9/page Order now As the heart is attached only by soft tissue it can change position in the diaphragm while it contracts and relaxes (diastole and systole) as in figure 2 and 3. Figure 2Figure 3For a better understanding of the structure and workings of the heart a heart dissection was performed, below are the conclusions gathered from the experiment. Conclusionso Distinguish between the dorsal and ventral sides of the heart. (The ventral side is more rounded than the dorsal side, and the thick walled arteries arise from this side). Note:The right and left atria (auricles) and right and left ventricles,Pulmonary artery and aorta arising from right and left ventricles,Anterior and posterior vena cava opening into right atrium,Coronary vessels in the heart wall,Figure 4 shows the ventral side of the heart clearly showing the pulmonary artery and aorta, the left and right atria and ventricles and the coronary vessels of the heart wall. Figure 4o Clamp posterior vena cava, then run water through anterior vena cava, from the water runs through the pulmonary artery, this is the route of the pulmonary circulation which receives deoxygenated blood from the systemic circulation and transported to the lungs to be oxygenated. Now run water through the pulmonary vein, which vessel does the water emerge?The water runs through the aorta, this is the route of the systemic circulation, the systemic circulation takes oxygenated blood away from the heart to oxygenise respiring cells throughout the body. Figure 5Figure 5 shows the systemic circulation in red and the pulmonary circulation in blue. o Expose the left ventricle by a longitudinal cut through ventral wall of the ventricle, note your findings. Through the cut in the left ventricle wall the following observations were recorded. (see figure 3) The left ventricular walls were visible, consisting of thick myocardium (cardiac muscle); the reason for the thickness of the left ventricle is because the left ventricle is responsible for the pumping of blood at high hydrostatic pressure throughout the systemic arterial system. .u9db23aeec6cd0b14f572de3a19faaa07 , .u9db23aeec6cd0b14f572de3a19faaa07 .postImageUrl , .u9db23aeec6cd0b14f572de3a19faaa07 .centered-text-area { min-height: 80px; position: relative; } .u9db23aeec6cd0b14f572de3a19faaa07 , .u9db23aeec6cd0b14f572de3a19faaa07:hover , .u9db23aeec6cd0b14f572de3a19faaa07:visited , .u9db23aeec6cd0b14f572de3a19faaa07:active { border:0!important; } .u9db23aeec6cd0b14f572de3a19faaa07 .clearfix:after { content: ""; display: table; clear: both; } .u9db23aeec6cd0b14f572de3a19faaa07 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u9db23aeec6cd0b14f572de3a19faaa07:active , .u9db23aeec6cd0b14f572de3a19faaa07:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u9db23aeec6cd0b14f572de3a19faaa07 .centered-text-area { width: 100%; position: relative ; } .u9db23aeec6cd0b14f572de3a19faaa07 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u9db23aeec6cd0b14f572de3a19faaa07 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u9db23aeec6cd0b14f572de3a19faaa07 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u9db23aeec6cd0b14f572de3a19faaa07:hover .ctaButton { background-color: #34495E!important; } .u9db23aeec6cd0b14f572de3a19faaa07 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u9db23aeec6cd0b14f572de3a19faaa07 .u9db23aeec6cd0b14f572de3a19faaa07-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u9db23aeec6cd0b14f572de3a19faaa07:after { content: ""; display: block; clear: both; } READ: Innocence of Scout in To Kill a Mockingbird EssayThe bicuspid valve, this valve is used to prevent backflow of blood from the left ventricle to the right atrium. Chordae tendinae, used to anchor the flaps of the bicuspid valve to the papillary muscle to prevent the valve turning inside out due to pressure. Papillary muscle, this is part of the myocardium of the ventricle and contains irregular shaped columns called trabeculane carnae. o Turn the heart upside down and run water into the ventricle through the slit you have cut, note your findings. The water ran through the aorta, as the left ventricle pumps blood into the aorta to be transferred via the systemic circulation. Figure 6 shows the interior of the heart. Figure 6o now turn the heart the right way up, run water through into the cut end of the aorta, note your findings The water appeared through the trabeculare carnae (irregular shaped columns in the papillary muscle) as a shower. o Cut open the left atrium and aorta by continuing your ventricular cut upwards, note your findings. Through the extended cut in the left ventricle the following were visible. Left atrium (auricle) this is the chamber which lies superior to the left ventricle, smaller than the right atrium (auricle) this houses the pulmonary veins which bring oxygenated blood from the lungs. The aortic valve (semi-lunar) this prevents backflow of blood from the aorta into the left ventricle. The pulmonary vein which returns oxygenated blood from the lungs to be pumped around the body in the systemic circulation. o Expose the interior of the right ventricle by a longitudinal slit through ventral wall, note your findings. The cut in the right ventricle exposed: (see figure 3) The right ventricle wall was visible consisting of thinner myocardium (cardiac muscle) than the left ventricle this is due to less hydrostatic pressure required to push blood into the pulmonary artery, this is known as the pulmonary circulation. Tricuspid valve this is to prevent backflow of blood into the right atrium from the right ventricle. Chordinae tendinae used to anchor the flaps of the tricuspid valve to the papillary muscle this is to prevent the valve been turned inside out by pressure. Papillary muscle part of the myocardium and contain fewer trabeculare carnae than the left ventricle. The right ventricle has a larger funnel shaped area of smooth wall known as the conus arteriosus or infunibulum. o Slit open the right atrium and pulmonary artery by continuing your ventricular slit upwards, note your findings. Through the extended slit in the right ventricle clearly visible was: The right atrium, this is larger than the left atrium the two great veins (superior and inferior) vena cava deposit deoxygenated blood from around the body into the right atria. The pulmonary valve, this prevents backflow of blood into the right ventricle. Coronary sinus which returns blood from the cardiac veins to the heart. o Note the opening of the coronary vein on the left hand side of the atrium; it is possible you may see a small oval depression this is the fossa ovalis, what do you suppose this is? The fossa ovalis is situated in the interatial septum (dividing wall of atria). During the stage of foetal development the blood flow is different from a newborn. The blood passes from the right atrium directly into the left atrium to be pumped around the body, this is made possible by a connecting tube called the foramen ovale, when a newborn baby inhales its first breath of air the pressure closes the foramen ovale and leaves behind the fossa ovalis, on some occasions a gap may be left this is referred to as a hole in the heart. Figure 7 shows the depression of the fossa ovalis situated in the right atriumFigure 7o Do you expect the foetal heart to differ from the adult heart? Why? Yes the foetal heart differs from the adult heart. .ueffedc032972b8f77bed3361b738fa8c , .ueffedc032972b8f77bed3361b738fa8c .postImageUrl , .ueffedc032972b8f77bed3361b738fa8c .centered-text-area { min-height: 80px; position: relative; } .ueffedc032972b8f77bed3361b738fa8c , .ueffedc032972b8f77bed3361b738fa8c:hover , .ueffedc032972b8f77bed3361b738fa8c:visited , .ueffedc032972b8f77bed3361b738fa8c:active { border:0!important; } .ueffedc032972b8f77bed3361b738fa8c .clearfix:after { content: ""; display: table; clear: both; } .ueffedc032972b8f77bed3361b738fa8c { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ueffedc032972b8f77bed3361b738fa8c:active , .ueffedc032972b8f77bed3361b738fa8c:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ueffedc032972b8f77bed3361b738fa8c .centered-text-area { width: 100%; position: relative ; } .ueffedc032972b8f77bed3361b738fa8c .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ueffedc032972b8f77bed3361b738fa8c .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ueffedc032972b8f77bed3361b738fa8c .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ueffedc032972b8f77bed3361b738fa8c:hover .ctaButton { background-color: #34495E!important; } .ueffedc032972b8f77bed3361b738fa8c .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ueffedc032972b8f77bed3361b738fa8c .ueffedc032972b8f77bed3361b738fa8c-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ueffedc032972b8f77bed3361b738fa8c:after { content: ""; display: block; clear: both; } READ: Legalize Marijuana EssayThe foetus although fully formed at twelve weeks is reliant on its mother until birth; the remaining twenty eight weeks are spent with maturation of the foetuss tissues and organs. The foetuss heart forms in the embryonic stage, beginning to beat at around week eight of gestation; although the heart is fully functional at this stage the lungs which play an essential part in the oxygenisation of blood in the cardiovascular system are not functional until birth. As the blood still needs to reoxygenise respiring cells a temporary substitute is the placenta, often referred to as the foetal lung it is responsible for filtering and supplying the foetus wi th oxygen and nutrients received from the maternal blood. For this process to take place the route the blood takes through the body needs to be diverted away from the lungs, as described above the foramen ovale passes blood through the interracial septum from the right atria to the left atria, this enables blood to bypass the right ventricle which intern stops the blood being pumped up the pulmonary artery. There is also a bypass system which connects the pulmonary trunk to the aorta; this called the ductus arteriosous which again enables blood to bypass the lungs. The ductus arteriosous and the foramen ovale close at birth with the first breath of the infant, this results in the two circulations of the heart (systemic and pulmonary) working alongside each other to bring homeostasis to the body.
