What is the largest organ in the human body?

The largest organ in the human body is the skin. It has a surface area of about 20 square feet in adults and accounts for about 15% of our body weight. The skin is composed of three main layers: the epidermis, dermis, and subcutaneous tissue.

The skin has a number of important functions, including protecting the body from physical, chemical, and microbial damage, regulating body temperature, and serving as a sensory organ to detect touch, pressure, pain, and temperature.

Other important organs in the human body include the liver, which is the largest internal organ, and the brain, which is the largest organ in the nervous system.
