Capillaries

Capillaries are the smallest blood vessels in the body, connecting arteries and veins. They have thin walls that allow nutrients, oxygen, and waste products to easily pass between blood and surrounding tissues. This exchange is vital for healthy cell function. Capillaries form an extensive network throughout the body, ensuring that every cell receives what it needs and can eliminate waste. Their design facilitates efficient transport, playing a crucial role in the circulatory system and overall health.
