Capillaries are the smallest blood vessels in the body and are responsible for allowing exchange of nutrients, gases, and waste products between the blood and nearby tissues. They have thin walls that allow for this exchange to occur. Veins and arteries have thicker walls and are responsible for carrying blood to and from the heart. Arterioles are small arteries that control blood flow to specific regions of the body.
