When body temperature rises-blood vessels in the skin?

When body temperature rises, blood vessels in the skin dilate, a process known as vasodilation. This increased blood flow to the skin facilitates heat loss through radiation and convection, helping to cool the body down. Additionally, sweating may occur, which further aids in temperature regulation as the evaporation of sweat removes heat from the body. Together, these responses help maintain homeostasis and prevent overheating.
