Subjective Short Answer

55. Do arteries always carry highly oxygenated blood? Explain your answer.ANSWER: No! The prominence of the systemic circulatory system sometimes creates the misunderstanding that

arteries carry highly oxygenated blood. But the characteristic of arteries is that they carry blood away from the heart. Thus, in the pulmonary circulatory system they actually carry low oxygen blood.

56. An individual has an issue with their red blood cells. Are they most likely to have an issue with their immunity, oxygen transport, or hemostasis? Explain your answer.ANSWER: As the red blood cells house the hemoglobin that transports the vast majority of the oxygen, they are

most likely to have an issue with oxygen transport. The immunity would be more the providence of the white blood cells, while hemostasis would be controlled by components of the plasma.

58. Chart the path of blood through the heart, including the valves passed.ANSWER: Blood enters the right atrium via the superior and inferior vena cavae. It then passes the right

atrioventricular valve and into the right ventricle. It is pumped from the right ventricle through the pulmonary valve to the lungs. Blood returns from the lungs to the left atrium, and passes through the left atrioventricular valve to the left ventricle. It is pumped out to the body through the aortic valve.
