Blood Circulation
Assignment Overview Please prepare a 2 page paper in which you discuss the flow of blood through the heart, and vascular system. Please be certain to include a discussion of: The chambers and valves of the heart and their function. The function of the major arteries and veins of the heart in the maintainance of blood flow. Be sure to include a discussion of the superior and inferior vena cava, aorta, pulmonary artery and vein, and coronary artery and vein. Discuss the causes of plaque build-up in coronary arteries and the implications of high cholesterol for the heart and circulation of blood. I want everyone to succeed in this course and am going to provide you with step-by-step instructions to help you achieve the highest possible grade on your paper. One of the major issues that I have come across is receiving papers from students that don’t meet the criteria for full points to be awarded. The major reason for this is failure to adequately address all of the stated objectives to the appropriate degree of a given assignment. A great way to overcome this problem is to begin your paper by examining the “weight” of each part of your paper. In each assignment, look to see how points are distributed AND what areas must be covered in your paper. I require the use of headings and sub-headings for your paper to organize the content. This helps to determine if all the criteria have been addressed and demonstrates the flow and organization of the content. Generally, APA Levels 1 and 3 are sufficient. For example: Let us assume that you are given instructions to write a 2 page paper. Imagine that there are 4 areas (or objectives or instructions), each worth 25% of your papers overall grade. You should make certain that your paper covers each topic equally. Here is an example: Cover Page (cover pages are required for ALL written academic work) Introduction Objective/instruction 1 (1/2 page) Objective/instruction 2 (1/2 page) Objective/instruction 3 (1/2 page) Objective/instruction 4 (1/2 page) Conclusion References References and Plagiarism For many of you, this may be your first academic course in quite some time. If this is the case, I encourage you to spend some time familiarizing yourself with the information found in the syllabus page. Please be certain that ALL submitted papers include a reference sheet. Remember that all sources used in the creation of your paper must be cited in your paper. Whenever you use the work of another, be it directly (taking actual direct quote from their work) or indirectly (putting their ideas into your own words), you need to cite in the text where you used their work. Academic work should also not look like a “ransom” note. That is, you should not cut & paste from multiple web-sources and try to paste it together into one big paper. If you are having difficulty understanding what constitutes plagiarism, please click on the following link:http://owl(dot)english(dot)purdue(dot)edu/owl/resource/589/01/ this web page, hosted by the Online Writing Lab (OWL) at Purdue University is a mini-tutorial that will help you to avoid inadvertent plagiarism. Assignment Expectations Page Length: 2 to 3 pages Format TUI encourages all students to comply with APA style and format guidelines for proper citation of references. For more information see Syllabus Home Page, APA Style and Format. Scholarly Content Your SLP and your case assignments are considered scholarly works. Your final work should include a MINIMUM of 10 peer reviewed (scholarly) sources. This does not mean that you must place 10 peer reviewed sources in each module of your Case/SLP. I anticipate that the nature of the questions which must be answered in this project will result in the accumulation of more than 10 references, but 10 is the minimum number. This means by the end of module 5, I should be able to go back and count AT A MINIMUM a total of 10 scholarly-peer reviewed publications in all of your submitted papers. If you are uncertain what a peer reviewed (scholarly) source is, go tohttp://www(dot)csuchico(dot)edu/lins/handouts/scholarly.pdf Please keep in mind that you should not use sources such as “Answers.com” or “Wikipedia” or “Wikianswers”. None of these are scholarly sources and they can be “modified” by any registered user which makes it unreliable. It could very well be that those who modify subjects in Wikipedia have a very good knowledge of the subject, however, since we have no way of knowing their credentials or intentions, we cannot guarantee that the source is reliable. It is a good place to start, but should not be used as factual in graduate writing. For graduate study, be sure to stick to peer reviewed journals and scientific sources.

Your paper should make use of appropriate headings and subheadings. You should not cut & paste the questions posed and answer them like a “Question and Answer” session. Your finished paper should read like an academic paper.
Blood Circulation
Name:
Institution:
The blood circulation in the heart of the human being can be separated into two parts, with the sole purpose of delivering the blood to the tissues and carrying the carbon dioxide to the lungs. The hearts muscles, which are myogenic in nature, contract the heart to push the blood in to major loops, which form the blood circulation within the body (Johns Hopkins Medicine, 2013). The first loop that is referred to as the systemic loop is responsible for the blood that delivers the oxygen to the body cells and collects the carbon dioxide. The other loop is called the pulmonary loop, is responsible for the oxygenation of the blood that comes from the body rich with carbon dioxide. The pulmonary loop is controlled by the right side of the heart while the systemic loop is controlled by the left side of the heart (University of Colorado, 2013).
In the systemic loop, the blood rich in oxygen from the lungs enters the left chamber of heart through the pulmonary vein by first getting into the left atrium. This is a much smaller chamber and when it fills up, it forces open the mitral valve, letting the blood flow into the left ventricle (Texas Heart Institute, 2013). The left ventricle is lined with more muscles than any other chamber in the heart, as it is responsible for pushing the blood to the rest of the body through the largest artery in the body called aorta, which is about an inch wide. The blood is delivered to the cells through a complex network of arteries and capillaries. Another network of the veins collects the carbon dioxide rich blood from the cells to the heart.
