biological barriers of the skin The first are physical barriers, such as the skin, body secretions and mucous membranes the second line of defense is the immune system specialized immune cells coordinate and execute attacks to kill germs that make it past the body's physical barriers.

I)functions of the integumentary system a) protection 1) chemical barrier 2) physical barrier 3) biological barrier b) body temperature regulation. The barrier function is an extremely important concept in skin care it describes the strength of the skin barrier and how well it protects skin from the external environment like the acid mantle on the surface of skin (a physical and chemical barrier that keeps out microorganisms and irritants), the barrier function serves a crucial protective function for the skin.
