 Consequently allowing blood flow to meet and match the metabolic demand of the tissue and prevents a mismatch between O2-demand O2-supply.Recent research has suggested that the locally produced vasodilators may be acting in a redundant manner, in which the antagonism of one dilator, be it pharmacologically or pathologically, may be compensated for by another in order to preserve blood flow to tissue.While the locus of blood flow control (at least in skeletal muscle tissue) is widely thought to reside at the level of the arteriole, research has begun to suggest that capillary endothelial cells may be coordinators of skeletal muscle blood flow during functional hyperaemia.
