The skin is a single organ system that is considered as the largest organ. It consists 15%-20% of the total weight of the body and covers 1.5-2 square meters of the external part of the body.
The integument or the cutaneous layer is composed of the epidermis and the dermis and the subcutaneous or the hypodermis is composed of loose connective tissue.
The integumentary system functions as a physical protective barrier against pathogens and prevents fluid loss. It has also sensory receptors that monitors the environment and its surroundings. It regulates temperature that helps maintain a constant body temperature thanks to the insulation of the layers of the skin.
It also synthesizes vitamin D that is important in the metabolism of calcium and bone formation. Lastly, it also plays a role in the attraction between sexes through the skin features, health indicators, and even hair pigmentation.
