Introduction
Our skin: we cherish it and worship its beauty, but take it for granted and misunderstand its importance for providing much of our needs. The integumentary system refers to the skin and its accessory structures, and it is responsible for much more than simply lending to your outward appearance. In the adult human body, the skin makes up about 16 percent of body weight and covers an area of 1.5 to 2m2. In fact, the skin and accessory structures are the largest organ system in the human body. It protects your inner organs, regulates your temperature and protects you from foreign invaders among other things, so you should keep it healthy. In addition to the structure and function of this large organ, the skin, you should be familiar with some of the diseases, disorders, and injuries that can affect this system.
