Principle
What Tasks might the structures you discovered have? Hair is used for touch and to limit heat loss through the skin. Dander is constantly shed from the outermost layer of skin as the skin underneath renews itself.
The ridges and lines in the skin provide better extensibility. They represent a unique, distinctive profile in each person. Pigments are particles of pigment contained in pigment cells. They prevent the harmful UV rays of sunlight from penetrating the lower layers of the skin. Sweat reaches the surface of the skin through the pores and evaporates there. This cools the body. Calluses form on the areas that are particularly exposed to stress, e.g. the soles of the feet or hands, and protect them from damage.
