Capillaries are the smallest blood vessels in the body, connecting arterioles and venules. They facilitate the exchange of oxygen, nutrients, and waste products between the blood and surrounding tissues. Their thin walls allow for this exchange to occur efficiently, playing a crucial role in the circulatory system. Capillaries are essential for maintaining healthy bodily functions by ensuring that cells receive necessary substances and can dispose of waste.
