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 endothelium provides a smooth surface for the flow of blood and regulates the movement of water and dissolved materials in the interstitial plasma between the blood and the tissues. The endothelium also produces molecules that discourage the blood from clotting unless there is a leak.lood flows out of the capillaries into the venules, which have little smooth muscle and are 10-200 Âµm. The blood flows from the venules into the veins. In addition to these blood vessels, the microcirculation also includes lymphatic capillaries and collecting ducts.
