Webb17 maj 2024 · Capillaries lead back to small vessels known as venules that flow into the larger veins and eventually back to the heart. Arteries, arterioles, venules, and veins are composed of three tunics known as the tunica intima, tunica media, and tunica externa. WebbCapillaries connect your arteries to your veins. Capillaries are the smallest type of blood vessel. They can be as tiny as 5 micrometers, which is less than a third of a hair's width.
WebbArterioles connect with even smaller blood vessels called capillaries. Through the thin walls of the capillaries, oxygen and nutrients pass from blood into tissues, and waste products pass from tissues into blood. From the capillaries, blood passes into venules, then into veins to return to the heart. WebbArteries transport blood away from the heart and branch into smaller vessels, forming arterioles. Arterioles distribute blood to capillary beds, the sites of exchange with the body tissues. Capillaries lead back to small vessels known as venules that flow into the larger veins and eventually back to the heart.
