What does skin look like?
The largest organ in humans is the skin. By her appearance can be judged on the health of the body, as well as it is an integral part of a beautiful appearance. After all, how our skin looks like depends on our well-being and mood. The skin consists of several layers, we list them:
- The epidermis is the outer layer of skin 0.05–1.5 mm thick. Its lower layer consists of living cells, which by their division ensure its constant updating. It is here that there are cells that produce melanin - a pigment that protects the skin from ultraviolet rays. The outer layer of the epidermis is made up of dead cells, which are peeled off all the time, thereby removing sticky dirt and micron organisms from the skin surface. Consequently, the main function of the epidermis is protective.
- Dermis - connective tissue with a thickness of 1-2.5 mm, consists of the outer papillary layer and the inner net. The papillary layer consists of loose connective tissue that forms the papillae with blood vessels. They penetrate the epidermis and nourish its cells (the cells of the epidermis do not have their own blood vessels). The mesh layer consists of collagen fibers, they give elasticity and elasticity to the skin.Here are the sebaceous and sweat glands, hair roots.
- Subcutaneous adipose tissue is represented by adipose tissue, up to several centimeters thick. It performs the role of the body heat regulator.
- Protective - the integrity of the skin provides reliable protection against pathogenic viruses and bacteria;
- Thermoregulatory - protects against cold on cool days, thanks to a layer of subcutaneous fat, and cools the body in the heat, due to sweating;
- Excretory - with the help of sweat and sebaceous glands, all unnecessary substances are excreted from the body;
- Exchange - with the help of the skin is the exchange and accumulation of fat, the formation of vitamin D;
- Receptor (sensitive) - in the skin are nerve fibers and sensory nerve endings. They perceive pain, pressure, touch, change in temperature.
If your skin looks worse, there may be many reasons. Some problems can be solved on their own, but often without the help of an experienced dermatologist is indispensable.
