C. Skin
Explanation
The skin is considered the largest organ of the human body by both weight and surface area. Here’s why: Surface Area: The skin covers the entire external surface of the body, serving as a protective barrier against physical, chemical, and biological threats. It envelops the body from head to toe, including all limbs and appendages. Weight: Although the skin may not seem as substantial as some internal organs, when you consider its overall surface area and thickness, it accounts for a significant portion of the body’s total weight. The skin’s weight varies depending on factors such as age, gender, and body size, but it typically makes up about 16% of an adult’s total body weight. Complex Structure: The skin is composed of multiple layers, including the epidermis, dermis, and subcutaneous tissue. Each layer has distinct functions, such as providing protection, regulating temperature, and housing sensory receptors. This complexity contributes to the skin’s significance as a vital organ in the body’s overall functioning. Overall, the skin’s extensive coverage and essential functions make it deserving of the title of the largest organ in the human body.
