You might be surprised to find out it’s the skin, which you might not think of as an organ. No matter how you think of it, your skin is very important. It covers and protects everything inside your body. Without skin, people’s muscles, bones, and organs would be hanging out all over the place. Skin holds everything together. It also:
protects our bodies
helps keep our bodies at just the right temperature
allows us to have the sense of touch

The skin is the outer covering of the body, also known as the epidermis, of an animal. It is the largest organ of the integumentary system made up of multiple layers of epithelial tissues, and guards the underlying muscles, bones, ligaments, internal organs.[1] The adjective cutaneous literally means “of the skin” (from Latin cutis, skin).

Because it interfaces with the environment, skin plays a very important role in protecting (the body) against pathogens. Its other functions are insulation, temperature regulation, sensation, synthesis of vitamin D, and the protection of vitamin B folates. Severely damaged skin will try to heal by forming scar tissue. This is often discolored and depigmented.

In humans, skin pigmentation varies among populations, and skin type can range from dry to oily.
