Arteries tend to have a lot of vascular anastomoses around body joints, such as the elbow and knee. Can you think of a reason why this would be beneficial?

Doctors strongly recommend that travelers on long airline flights stretch their legs or stand up and walk down the aisle periodically in order to prevent development of a clot in their lower legs. This is a condition known as Deep Vein Thrombosis (DVT). Explain why this condition is more likely to occur in someone who is sitting still for long periods of time such as on an airplane.
Several years ago, the deaths of several airline travelers led to the warning about “economic-class syndrome.” The idea is that economic-class passengers do not have as much leg room as passengers in more expensive seats, so they are more likely to sit essentially motionless for long periods of flights-conditions that may allow blood to pool and clots to form in the legs. This condition is called deep-vein thrombosis, or DVT. Given what you know about blood flow in the veins, explain why periodically getting up and moving around in a plane’s cabin during a long flight may lower the risk that a cloth will form.
In bypass surgery, the cardiovascular surgeon will collect a portion of the living saphenous vein from the patient and implant it as a shunt between the same patient's ascending aorta and distal coronary artery. What do you think would happen to the vein tissue after a few weeks of exposing the vein cells to arterial pressure and flow conditions? (minimum 30 words)

- The aorta, the largest artery in the body (in diameter), carries oxygen-rich blood away from the heart as it begins the systemic blood flow circuit throughout the body. Owing to the fact that the aorta connects directly to the heart, the blood pressure (BP) inside the aorta is very high. As blood travels further from the heart, the BP gradually decreases. For example, the BP in the aorta is higher than in the brachial artery; the BP in the brachial artery is greater than in the antecubital artery; the BP in the antecubital artery is greater than in the radial artery. Based on the understanding that walls of the aorta are subjected to extreme outward pressure, hypothesize the order of specific tissue types one would expect to find in the aorta (from deep to superficial) and explain your rationalearrow_forwardA blood cell drifts along with the flow of blood through an artery that has a section partially blocked by fatty deposits on the artery wall.As the blood cell moves from the wide region of the artery into the narrow region (with the wall deposits), it experiences... *arrow_forwardLo n the surgical procedure called a bypass graft, a vessel is removed from a patient and used to make a vascular bridge that bypasses one of that patient's blocked arteries.
