The dermis lies below the epidermis and the epidermis is the outermost or lastlayer of the skin. The Dermis is thicker than the Epidermis and consists of the hair follicles, bloodvessels and various glands. Hypodermis is the third layer of the skin and it is not a part of theintegumentary system but helps in the functioning of the skin therefore, it is being discussed here.The function of the hypodermis is to attach the skin to the underlying tissues. This layer alsoprovides insulation and padding for the body as one half of this layer is made up of fat.Glands of the skin include the sebaceous glands and sweat glands. The sweat secreted by the sweatglands cools down the body due to its evaporation. Sebaceous glands secrete an oily substancewhich protects the hair and the skin and this oily substance is known as the sebum.
Hair and nailsare additional organs of the integumentary system and these are mostly made up Keratin. Hair trapsair around the body and which then acts as an insulating layer. The hair inside the nasal chambersand the eyelashes protect the nose and the eye from dust particles entering into them. Nails are ahard and thick layer of keratinized cells and they protects the tips of fingers and toes.The integumentary system and other systemsThe skin as well as other different parts of the integumentary system work with other systems in thebody to support and maintain the conditions of the tissues, organs and cells so that they are able tofunction properly.
