Microcirculation refers to the flow of blood through the smallest blood vessels in the body, including capillaries, arterioles, and venules. This process is essential for delivering oxygen and nutrients to tissues while removing waste products. It plays a crucial role in maintaining overall health and supporting cellular functions. The regulation of microcirculation is influenced by various factors, such as blood pressure, temperature, and hormones. Proper microcirculation is vital for healing, immune response, and tissue health. Impairments in this system can lead to conditions like diabetes and peripheral artery disease, affecting overall well-being.
