vasodilation of blood vessels.
When the body starts to overheat, the blood vessels near the surface of the skin dilate, allowing more blood to flow near the skin's surface. This process is known as vasodilation. By increasing blood flow to the surface, the body aims to release excess heat to the surrounding environment. The heat from the core of the body is transferred to the skin, and then dissipates through radiation, conduction, and convection.
Vasodilation helps in the regulation of body temperature by increasing heat loss through the skin. The increased blood flow brings warm blood from the core of the body closer to the skin, facilitating the transfer of heat to the surroundings. This process causes the skin to appear redder and feel warmer to the touch.
Together with perspiration, vasodilation assists in cooling down the body when it is too hot. Perspiration helps to cool the body through evaporation, while vasodilation enhances the heat transfer to the environment. These mechanisms work in synergy to maintain a constant and safe body temperature.
When the human body begins to overheat, it attempt to maintain a constant temperature through several mechanisms, including perspiration. Another mechanism with the same affect is
