WebHumans control their body temperature in a process called thermoregulation. It is essential the internal body temperature is maintained at 37\degree \text {C} 37°C in order for enzymes to work effectively. Heat energy is released into the body during respiration and then lost into its surroundings.
WebIn hot environments, blood vessels under the surface of the skin dilate to allow more blood to flow through them. This causes more heat to be lost from the blood to the environment so body temperature decreases to a normal level. In cold environments, the opposite occurs and the blood vessels under the surface of the skin constrict.
