What is the largest organ in the human body?

• A. Liver
• B. Heart
• C. Skin
• D. Lungs

Answer: (C)

The largest organ in the human body is the skin. It serves several vital functions, including protection against environmental hazards, regulation of body temperature, and sensation. Covering the entire body's surface, the skin comprises multiple layers, the outermost being the epidermis, followed by the dermis, and then the subcutaneous tissue or hypodermis. The surface area of the skin in an average adult can be around 1.5 to 2 square meters, making it considerably larger than other organs. In comparison, while the liver is notably large and performs crucial metabolic functions, it is not larger than the skin in terms of area. The heart, although important as the central organ of the circulatory system, is much smaller than the skin. Similarly, the lungs, which are essential for respiration, also do not match the surface area of the skin when considering the total body coverage. Therefore, the skin's extensive surface area and multifunctionality make it the largest organ in the human body.
