sweating and dilation of cutaneous blood vessels.

Explanation:

The human body, in an attempt to achieve thermal equilibrium, always gives heat to a colder body that is in contact with it, that is, heat passes from one body to another because of the temperature difference between them. This process is characterized by the human body's attempt to achieve temperature control.

When the body needs to lose heat, the blood passing through the hypothalamus is hotter than normal, at which point the heat-loss center activates. This region inhibits the center of heat production, leading to dilation of the cutaneous blood vessels increasing the blood flow, which can often be enough to regulate the temperature. If the body remains warm, a signal through the sympathetic nerves stimulates the body's sweat glands, causing sweating. Sweat has the function of carrying water out of the body and since this liquid is a good conductor of heat, its evaporation causes the body to cool down.
