Flashcard 291: What is the primary mechanism regulating blood flow to the skin?

Answer: Sympathetic innervation

Extra: Skin blood flow is primarily under extrinsic (sympathetic) control for the purpose of thermoregulation. Unlike the heart, brain, and kidneys, the skin exhibits minimal intrinsic autoregulation.

Answer: Decreased pulse pressure

Flashcard 298: What equation may be used to calculate O2 delivery to tissues? O2 delivery = _____
