Q
peripheral vasodilation
A
What happens during peripheral vasodilation?
Vasodilation is a mechanism to enhance blood flow to areas of the body that are lacking
oxygen and/or nutrients. The vasodilation causes a decrease in systemic vascular
resistance (SVR) and an increase in blood flow, resulting in a reduction of blood pressure.

Q
peripheral vasoconstriction
A
Peripheral vasoconstriction is an important autonomic response
to cold exposure, which restricts heat transfer from the core to the
environment through the skin. Peripheral vasoconstriction is more
dependent on core than on skin temperature (cf.
