A. Venules.
Capillaries are small, thin-walled vessels that link arterioles (small arteries) and venules (small veins). They are responsible for the exchange of nutrients and waste products between the blood and surrounding tissues. The walls of capillaries are only one-cell thick, which allows for the efficient diffusion of gases, nutrients, and waste products. After blood has passed through the capillaries, it is collected by venules and transported back to the heart through larger veins.
