Intravital microscopy revealed that 65% of all the m. cremaster's capillary bed were perfused at rest. The capillary functional reserve may play an important part in the topographical heterogeneity of the perfusion. The heterogeneity is a passive mechanism in an increasing number of perfused capillaries, i.e. the "capillary recruitment".
