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.
Capillary beds can consist of two types of vessels: true capillaries, which branch from arterioles and provide exchange between cells and the blood, and short vessels that directly connect the arterioles and venules at opposite ends of the beds, metarterioles, only found in the mesenteric circulation.ymph capillaries connect with larger lymph vessels to drain lymph collected in the microcirculation. During early embryonic development new capillaries are formed through vasculogenesis, the process of blood vessel formation that occurs through a de novo production of endothelial cells which then form vascular tubes.
