A metarteriole is a vessel that emerges from an arteriole and supplies a group of 10 to 100 capillaries. Both the arteriole and the proximal portion of the metarterioles are surrounded by smooth muscle fibers whose contractions and relaxations regulate blood flow through the capillary bed.icrocirculation is a term coined to collectively describe the flow of blood through arterioles, capillaries and the venules (Fig. 2). (click image for larger view). Figure 1. The major paths of blood flow through pulmonary and systemic circulatory systems.
The flow of blood in the capillaries is controlled by structures called precapillary sphincters. These structures are located between arterioles and capillaries and contain muscle fibers that allow them to contract. When the sphincters are open, blood flows freely to the capillary beds of body tissue.
