Which of these statements correctly describes arteries?

Question

Quizplus · Accepted Answer

Arteries act as pressure reservoirs to provide the driving force for blood when the heart is relaxing. They are able to maintain their blood pressure due to their elastic walls that expand and contract to accommodate the surge of blood with each heartbeat. A is incorrect because large radius would actually decrease the velocity of blood flow, not increase it. B is incorrect because veins, not arteries, act as blood reservoirs due to their capacity to stretch and hold large volumes of blood. D is incorrect because the site of exchange between blood and tissues is primarily the capillaries, not arteries.
