The integumentary system forms the external surface of the body. The largest organ of this system, and of the body in general, is the skin. Besides the skin, the integumentary system also comprises the skin appendages (hair, nails, sweat and sebaceous glands), subcutaneous tissue, deep fascia, and breasts.
This video tutorial will explain the layers, structure and function of the skin, its appendages, and other parts of the integumentary system.
Memorize the epidermal layers of the skin easily with the help of this video.
