What are the major resistance vessels of the body

Question

Quizplus · Accepted Answer

Arterioles are considered the major resistance vessels of the body as they are responsible for regulating blood flow and controlling blood pressure. They have the ability to constrict or dilate in response to signals from the nervous system or hormones, thereby controlling the amount of blood that flows through them and ultimately affecting the resistance to blood flow in the body. While arteries and veins also contribute to resistance to blood flow, arterioles have the most significant impact due to their small size and ability to constrict and dilate rapidly. Capillaries, on the other hand, are not generally considered resistance vessels as they offer little resistance to blood flow due to their small size and simple structure.
