Skin functions and thermoregulation.

Skin is a natural barrier between the internal body and the external environment. She is the outer cover of the vertebral bodies. Has a number of features such as:
– respiratory (gas exchange processes pass through it);
– excretory (carried out with the help of sweat and sebaceous glands);
– conversion of solar energy into vitamin D;
– reserve in the subcutaneous fat layer of energy materials;
– protective (prevents pathogenic bacteria from directly entering the body);
– thermoregulation (one of the important functions, due to which a comfortable body temperature is maintained, regardless of environmental conditions);
– receptor (receptors directly transmit information to the brain through nerve impulses);
– self-cleaning (due to contact with the outside world, the skin is invisibly renewed).
