Microcirculation refers to the circulation of blood within the small blood vessels embedded in body organs. Microcirculation blood vessels consists of innervated vessels called arterioles on the arterial side of microcirculation and venules, which transport blood from capillaries to veins. These blood vessels have the function of distribution blood in tissues. The control of circulation in the microcirculation is under the control of two factors: Local control and the nervous system (Fung & Zwerfach, 2001).
The nervous system regulates microcirculation through sympathetic stimulation that involves hormones like nor epinephrine and epinephrine exerting their effect on smooth muscle. Local control mechanisms
