PATHOLOGY

Detailed explanation-1: -Share on Pinterest Vasodilation may occur when a person exercises. Vasodilation refers to the widening of the arteries and large blood vessels. It is a natural process that occurs in response to low oxygen levels or increases in body temperature.

Detailed explanation-2: -Direct warming of the skin causes a vasodilation dependent on the degree and the speed of the local warming (5, 29, 58). When local temperature is rapidly increased to 42°C and maintained at that level thereafter, skin blood flow in that region typically increases to its maximum (39, 76).

Detailed explanation-3: -Vasodilation is the widening of blood vessels as a result of the relaxation of the blood vessel’s muscular walls. Vasodilation is a mechanism to enhance blood flow to areas of the body that are lacking oxygen and/or nutrients.
