Microcirculation refers to the flow of blood through the smallest blood vessels in the body, including capillaries, arterioles, and venules. This process is crucial for delivering oxygen and nutrients to tissues while removing waste products. It plays a vital role in maintaining overall health and supporting cellular functions. The regulation of microcirculation is influenced by various factors, such as blood pressure, vascular resistance, and the surrounding tissue's metabolic needs. Proper microcirculation is essential for healing, immune response, and temperature regulation, making it a key component of the body's circulatory system.
