Hye,2nd posting,let's begin our look at the part of the body by looking first at the skin.We all know what hands and eyes are for,but what does the skin do? It is easy to see that the skin is a cover for the inner parts of the body.But like many other organs of the body,it has several jobs or functions.The skin is an organ that senses changes around you,and helps to keep the body temperature steady.The skin is a barrier against germs.It also removes some substances from the body and stores others temporarily.
We really should talk about ur skins,for you have two of them.The outer skin that u can see and touch is the epidermis.it is skin in which the living material has been replaced by a hard substance called keratin.as u grasp,touch,rub and wash,the cells of the epidermis are worn away,however,for the lower skin or dermis constantly produces new cell. These called fresh epidermis.
