Question

at any given time, more than half the total blood volume is found in __________. a capillaries b arteries and arterioles c venules and veins d arterioles and venules

Explanation:

Veins are known as capacitance vessels. They can hold a large volume of blood. At any given time, more than half of the total blood volume is present in venules and veins. Capillaries are the site of exchange but do not hold the majority of blood volume. Arteries and arterioles carry blood away from the heart but have a smaller volume compared to veins. Arterioles and venules together also do not hold the majority of blood volume like veins and venules do.

Answer:

C. venules and veins
