Afferent veins are small blood vessels that carry blood back to the heart from the peripheral tissues, such as muscles and skin. They are typically thin-walled and have thinner walls compared to venules and larger veins. Afferent veins have smooth muscle layers that help regulate blood flow and pressure, allowing them to control the amount of blood returning to the heart. These veins play a crucial role in maintaining proper circulation and blood pressure by adjusting their diameter according to the body's needs.
