Question

explain the sweating mechanism of human body to cintrol the temperature of the body

Answer 1

Body temperatures can rise due to increased metabolism or external environmental factors. This requires that some heat be lost to lower the temperature levels to normal. Temperature control mechanisms employ such mechanisms as sweating. Sweating helps cool the body through the following process:

When core body temperature is high,the temperature control center in the brain, the hypothalamus, sends nerve impulses to to the sweat glands and other temperature regulatory organs such as the blood vessels. The nerve impulses initiates the sweat glands to start producing sweat (which is water and salt). The sweat then pours out onto the skin and when the water in it evaporates heat is carried away from the skin through latent heat of vaporization.

Answer 2

Answer:

1. When we get sweat,the droplets of sweat evaporates from the surface of our body by absorbing the heat from our body.
2. Thus the particles of liquids (sweat) extract energy from our body and and escapes into the surroundings.
3. As the energy from our body is is lost in the form of heat energy, the body becomes cool and we feel comfortable.
