What is the major site of sympathetic blood flow control (resistance changes)?

Question

Quizplus · Accepted Answer

Arterioles are the major site of sympathetic blood flow control, as they have the ability to constrict or dilate in response to sympathetic signals. This can result in increased or decreased blood flow to specific tissues, organs, or regions of the body, depending on the needs of the body at any given time. Capillaries are too small to be selectively regulated by sympathetic nerves and metarterioles are precapillary sphincters that regulate blood flow to capillaries. Arteries are too proximal to regulate blood flow precisely to organs and tissues.
