Microcirculation

Meaning

Microcirculation is the essential component of the circulatory system comprising the smallest blood vessels, specifically the arterioles, capillaries, and venules, responsible for the direct exchange of gases, nutrients, and waste products between the blood and the surrounding tissues. This network is crucial for tissue health, as it delivers oxygen and hormones directly to the cellular environment and removes metabolic byproducts. Dysfunction in microcirculation, often seen in conditions like diabetes or hypertension, severely compromises cellular function and overall organ vitality.
