Which small vessels branch from arteries and lead to capillaries?

The main concept is how blood moves from arteries into the tiny vessels that feed tissues. Arterioles are the small vessels that branch from arteries and lead into the capillary networks. Their walls contain smooth muscle, allowing them to constrict or dilate to regulate blood flow and pressure reaching the capillaries, which is essential for proper nutrient and gas exchange. Capillaries are the sites of exchange themselves, and venules collect blood after it passes through capillaries. The aorta is the large main artery, not the small vessel that directly links to capillaries.
