Control and Coordination of Vasomotor Tone in the Microcirculation

摘要: The blood vascular system consists in a complex network of vessels that is mainly intended to provide oxygen and nutrients all individual cells peripheral tissues help dispose metabolic wastes. Several distinct functional compartments can be distinguished the network: arteries, arterioles, capillaries, venules veins. Conduit arteries (diameter, 1 several millimeters) carry away from heart through divergent arborescence reaches penetrates into via feed 100 500 μm) (Davis et al., 1986; Segal, 2000, 2005). These muscular give rise arterioles < l00 μm), which control coordinate flow distribution such way each capillary correctly supplied at proper pressure (Mulvany, 1990; This part composed capillaries embedded within organ irrigated called microcirculation 2005; Lockhart 2009). Finally, veins back convergent arborescence.
