There are two major sections of the skin, the epidermis and the dermis . The epidermis is the skin that you can see right now, the stuff on the outside. Actually, the cells that make up your outer epidermis layer are dead and, therefore, are always being replaced by the cells from the dermis that move outward. The skin covering your body is one example of a tissue, or a group of similar cells that perform a specific function. There are many different kinds of tissue in your body.
Skin is a type of tissue called epithelium .
Other epithelium tissues include lung tissue, stomach tissue, and blood vessel tissue. These all protect your body from injury and infection. But, that's not all. You also have connective tissue in you, holding everything together. They support everything in your body so you can walk and move around like everybody else.
