The epidermis is the outer layer of skin, 1-2 millimeters thick, whose main function is a protective barrier from external irritants. The epidermis is what we see.
Skin is an important organ of the human body, which not only occupies a huge area of the body (about 17%), but also performs a large number of functions. It is believed that regeneration is the main ability of the skin, but others are worth noting:
- the skin protects important internal organs and human systems from any type of damage, as well as from ingestion of pathogenic microorganisms;
- participates in the process of thermoregulation, protects the body from hypothermia or overheating;
- processes of water-salt metabolism occur in the skin;
- it is a blood depot (up to 1 liter of blood can be stored in the vessels of the skin);
- there are a large number of nerve endings on the skin;
- skin absorbs up to 2% oxygen.
