The role of the skin RAS in the local regulation of capillary blood flow and cutaneous water conservation/loss. a A normal condition in the presence of ATRAP at a normal temperature, b a condition in the presence of ATRAP with the activated skin RAS at a low temperature, c a condition in the absence of ATRAP with the activated skin RAS at a low temperature, and d a condition in the absence of ATRAP with the activated skin RAS at a high temperature.
