Like transpiration in plants mammal's hypothalamus makes sweat glands functional and mammal's body secretes sweat which on evaporation decreases the body temperature
In both the process ,liquid evaporates and carries away the heat and also produce cooling sensation on the surface of the mammal or object
Explanation:
In the process of transpiration (which is a thermodynamic process), when a liquid or gas transpires or evaporates from the surface of any structure then it carries away the heat energy contained in that structure and also reduces the radiative heat flux coming into the that structure thereby producing a colling effect.
Like wise , sweat released by the gland in skin of mammals evaporates leaving a cooling effect on the surface or body.
