Which is the largest sense organ?

The nose? Or maybe the ears? No, of course it's the skin. The skin is the largest sense organ in man! It is a waterproof, strong, padded layer that protects against the effects of heat, cold, sun and germs. A protective coat that needs sufficient care from inside and outside!

Everyone has their own skin pattern of bows, bows or whirls. The skin indicates how old a person is, whether he feels well or is ill. When you are angry, you turn red, when you look terribly pale. Discolouration of the skin are usually signs of disease.

The skin is a multi-layered organ

  • The epidermis
  • The dermis
  • The subcutaneous tissue

The epidermis is about as thin as a sheet of paper. It protects the organism from injury, dehydration and the entry of pathogens. It consists of covering tissue, which clearly shows a structure in two layers: In the lower germ layer, new cells are continuously formed, which are forced outward by subsequent cells in the horny layer, keratinate, die off and abschilfern. In this way, our skin renews unnoticed about once a month.

The epidermis is interlocked with the thick dermis. In it are muscles and fine blood vessels, numerous sensory organs, gnawed glands that produce sweat. Other glands produce sebum and are located near the hair roots. The sebum lubricates the hair and skin, leaving the skin supple.

The subcutaneous tissue is the thickest of the three layers. It contains fatty tissue. This acts a cushion against pressure and shock. It also serves as a thermal insulation and reduces the heat loss of the body. In addition, this fat is a nutrient reserve.

The skin has a double task

On the one hand, it acts as a protective cover for the body, protects against dehydration, cooling and penetration of bacteria, absorbs pressure and shock. On the other hand, it establishes the connection to the outside world through tiny sensory organs that convey pressure, pain and temperature sensations.
