A)adhesion junctions

D)semilunar valve

Question

Quizplus · Accepted Answer

Precapillary sphincters are small circular muscles at the entrance of capillary beds that can open or close to regulate blood flow into the capillaries. This helps to control the distribution of blood within the body's tissues and organs. Adhesion junctions are specialized areas of cell-to-cell contact that help cells stick together, but do not control blood flow. Arteriovenous shunts are abnormal blood vessel connections that bypass the capillaries, and semilunar valves are found in the heart and control the flow of blood between the chambers.
