Skin- The largest and primary protective organ of the human body is the skin, which is a part of the integumentary system. It serves as a first-order physical barrier against the outside environment, covering the entire external surface of the body. It makes up about a quarter of your total body weight. Its surface area ranges from 1.5 to 2m². The superficial epidermis and the deeper dermis are the two layers that make up the skin.
