capillary density

Capillary density refers to the number of tiny blood vessels, called capillaries, in a specific amount of tissue. It indicates how well the tissue can receive oxygen and nutrients, as well as remove waste products. Higher capillary density means more capillaries are available, improving blood flow and efficiency of nutrient exchange. This is especially important in muscles and organs that require a lot of oxygen, like the heart and brain. Adequate capillary density supports overall tissue health and function, while lower density can be associated with limited blood supply and reduced performance or healing.
