Capillary exchange

Capillary exchange refers to the process by which nutrients, gases, and waste products move between blood and surrounding tissues through tiny blood vessels called capillaries. These vessels have thin walls that allow oxygen and nutrients to pass from the blood into cells, while waste products like carbon dioxide move from the cells back into the blood. This exchange is essential for maintaining healthy tissue and overall bodily functions, ensuring that cells receive what they need and help eliminate waste. It plays a crucial role in our body's ability to sustain life and respond to various needs.
