Differential influences of CNS and superficial body temperatures on the partition of cutaneous blood flow between capillaries and arteriovenous anastomoses (AVA's).
Radioactive microsphere measurements of blood flow in the hindlimb of the conscious sheep indicate that CNS temperatures have a potent influence on blood flow through cutaneous AVA's but not capillaries, and vice versa for superficial body temperatures.
