Capillaries are responsible for the exchange of oxygen and metabolic waste due to their thin walls and close proximity to tissues. Oxygen diffuses from the capillaries into the tissues, while waste products like carbon dioxide diffuse from the tissues into the capillaries to be carried away. Arteries carry oxygenated blood away from the heart, while veins carry deoxygenated blood back to the heart. Venules are small veins that connect capillaries to larger veins.
