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.
Arterioles carry the blood to the capillaries, which are not innervated, have no smooth muscle, and are about 5-8 Âµm in diameter. Blood 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.hen the flow of substances goes from the bloodstream or the capillary to the interstitial space or interstitium, the process is called filtration. This kind of movement is favored by blood hydrostatic pressure (BHP) and interstitial fluid osmotic pressure (IFOP).
