Cardiovascular Case Study 2021-Graded A+

Document Content and Description Below

Part I - Heart Anatomy Questions: 1. Label figure 1. Please see diagram. 2. Label blood vessels. Please see diagram. 3. List the order that blood passes through each of the structures you've labelled, beginning with the inferior and superior vena cava. Deoxygenated blood enters the heart from the body through the vena cava. This blood is then pumped into the right atrium, through the tricuspid valve, and into the right ventricle. The blood is then pumped through the semilunar valve, out of the heart, and through the pulmonary artery and into the lungs, where it becomes oxygenated. The blood then travels to the left atrium via the pulmonary vein. From the left atrium, the blood passes through the bicuspid valve and into the left ventricle. The blood leaves the left ventricle through the aorta and travels to the rest of the body. As the blood travels around the body, it deposits oxygen and collects carbon dioxide. It is during this process, that the blood becomes deoxygenated. The vena cava then helps get this deoxygenated blood back up to the right atrium, where the process starts all over. 4. Use markers, crayons, or colored pencils to color the chambers of the heart and blood vessels either red or blue, depending on how highly oxygenated the blood contained within them is. Highly oxygenated blood is bright red, so color areas containing highly oxygenated blood red and those containing blood with lower oxygen levels blue. Please see diagram. 5. Explain why there is a difference in oxygen content of the blood on the two sides of the heart. The right side of the heart contains deoxygenated blood. The left side of the heart contains oxygenated blood. The reason for this is because the right atrium collects the deoxygenated blood (used blood) that has been pumped around the body, depositing oxygen and collecting carbon dioxide. Blood becomes oxygenated after it has been pumped into the lungs. This blood is then pumped into the left ventricle, through the aorta, and out to the rest of the body. Part II- Circuits of Blood Flow Questions: 1. In your own words, define pulmonary circuit and systemic circuit. The best way I can think of to describe the cardiovascular system is to think of it like plumbing in a house. Our bodies are the house and our hearts are similar to plumbing because it has two pumps with pipes attached to it. Those pipes are our bodies pulmonary and systemic circuits that permits the circulation of blood which begins and ends at the heart. Systemic circulation describes the left side of heart that brings blood to and from the body. Pulmonary circulation describes the right side of heart and the vessels that bring blood to and from the lungs for the purpose of oxygen exchange. 2. Based on where they must pump blood to, which side of the heart do you think must pump harder, right or left? Explain your answer and use anatomical evidence from the heart to support your argument. The left ventricle of your heart is larger because it has thicker walls in comparison to the right ventricle. This is because it must pump t
