INTEGUMENTARY SYSTEM

The integumentary is the covering of the human body and its’ most apparent function is physical protection: skin – a tightly knit network of cells, with each layer contributing to its strength. The epidermis has an outermost layer created by layers of dead keratin that can withstand wear and tear of the outer environment, the dermis provides the epidermis with blood supply and has nerves that bring danger to attention amongst other functions; hypodermis provides physical cushioning to any mechanical trauma through adipose storage; glands secrete protective films throughout the body; nails protect the digits; hairs throughout the body filter harmful particles from entering the eyes, ears, nose, etc.
