The largest organ of the human body is (c) Skin. Covering an average adult’s body surface area of about 1.5 to 2 square meters, the skin serves as a protective barrier against external threats such as pathogens, chemicals, and physical injury. It consists of multiple layers, including the epidermis, dermis, and hypodermis, each with distinct functions.
Apart from protection, the skin regulates body temperature through sweating and blood flow, senses touch, pressure, temperature, and pain, and plays a crucial role in synthesizing vitamin D when exposed to sunlight. Additionally, the skin houses a variety of specialized cells that contribute to immune surveillance and defense against infections.
While the brain (a), heart (b), and liver (d) are vital organs with essential functions, none match the skin’s extensive surface area and diverse roles in maintaining overall health and homeostasis in the human body.
