Homeostasis is a state of stable internal environment that is mainteined by an organism. Maintaining the stable temperature (thermoregulation) is one of the examples of maintening the homeostasis and it is achieved by the skin in humans. The skin control of the temperature:

1.sweating- the sweat glands of the dermis secrete sweat that lower the temperature via evaporation,

2. skin circulation-vasoconstriction and vasodilation of the blood vessels inside the skin regulates the temperature. For example, when the body temperature is high, the blood vessels dilate, allowing heat to be released through the surface of the skin,

3. insulation by the subcutaneous layer of the skin which is made of  fat cells and fibrous tissue

4.piloerection.

There are 4 ways of the heat loss from the skin:

1.radiation

2.conduction

3.convection

4.evaporation

Answer:

Explanation:

Homeostasis is the state of equilibrium in the body. It is a process in which living organisms body maintain physical, chemical conditions balance or stability.

The skin help to maintain thermoregulation in four ways and they are;

Sweating: when there is much heat, the body tend to increase heat loss by producing sweat and causing sweating evaporation which help to maintain body temperature in the body.

Shivering: it occur when there is to much cold. When there is cold, the body try to maintain temperature stability by causing involuntary movement of muscles which intend lead to heat loss.

Vasoconstriction: the blood supply to skin help the skin in thermoregulation. When the blood vessels constricts, heat is retained and no heat loss.

Vasodilation: the skin regulate it body temperature through vasodilation. When the blood vessels that supply blood to the skin dilate, heat is loss.
