Passage 6

The skin is a person's first line of defense against all external elements. It is the largest organ of the human body, which is usually sixteen percent of the total body weight.The skin protects muscles, bones and other internal organs.It is made up of three layers, namely, the epidermis, the dermis and the subcutaneous layer.New skin cells are formed underneath the epidermis, and as these form, older cells are pushed upward.As a person's skin cells get older and tougher, about 30，000 of these dead cells are sloughed off every minute.The skin continuously makes new cells and gets rid of old ones.Hence, a normal person can shed up to four kilograms of dead skin cells per year.

Question
