Capillaries are the smallest blood vessels in the circulatory system, serving as the primary site for the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues. Their thin walls facilitate this exchange, allowing oxygen to diffuse into cells while carbon dioxide and other metabolic waste products move into the bloodstream. Capillaries connect arterioles, which carry blood away from the heart, to venules, which return blood to the heart, playing a crucial role in maintaining overall circulation and homeostasis.
