Capillaries are the smallest blood vessels in the body, connecting arterioles and venules. They play a crucial role in the circulatory system by facilitating the exchange of oxygen, carbon dioxide, nutrients, and waste products between blood and surrounding tissues. Their thin walls, composed of a single layer of endothelial cells, allow for efficient diffusion and fluid movement. This network of capillaries is vital for maintaining tissue health and homeostasis.
