Quizplus · Accepted Answer

Arteries play an important role in controlling blood flow and blood pressure. They are responsible for carrying oxygenated blood from the heart to the body's tissues, and their muscular walls can contract or dilate to regulate blood flow and pressure. Veins also have one-way valves that help control blood flow, but they are not as effective at regulating pressure. Capillaries are responsible for exchanging nutrients and waste products between the bloodstream and the body's tissues, but they do not have a direct role in controlling blood pressure.
