The common use of such terms as "venous tone" and "venous pooling" neglects the fact that the systemic venous system is really subdivided into three major parallel compartments; the splanchnic, skeletal muscle, and cutaneous venous beds. Transfer of blood into and out of each compartment is controlled by a variety of different factors. Cutaneous veins, under neurohumoral control, perform an exclusively thermoregulatory function and will "pool" significant quantities of blood away from the central circulation only during body warming, especially with exercise in a hot environment. The volume of blood in the veins of skeletal muscle is determined almost completely
