Name the largest organ of the human body.

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

Answer: (D)

The largest organ of the human body is the skin. It serves as a vital barrier that protects the internal structures from external elements, such as pathogens, harmful substances, and extreme temperatures. The skin is not only a protective layer but also plays roles in sensation, thermoregulation, and synthesis of vitamin D. With a surface area that can measure approximately 1.5 to 2 square meters in adults, it far exceeds the size of other organs such as the liver, lungs, or heart. Each of these organs serves crucial functions, but none can match the extensive coverage and multi-functional capabilities of the skin.
