Arterioles and venules have a vasa vasorum to provide nutrients to their outer walls, whereas the inner walls receive nutrients from blood in the lumen. False

Explanation:

Arteries and veins transport blood in two distinct circuits: the systemic circuit and the pulmonary circuit. Arteries carry blood from the heart, and then they transforme into ever-smaller vessels, such as arterioles and venules. More frequent in veins than arteries, we found a vasa vasorum, which is called the vessels of the vessels. This is a small network of blood vessels that supply the walls of them.
