True or False: Skin is the largest organ of the human body.

Skin is indeed the largest organ of the human body. It serves several critical functions, including protection against environmental hazards, regulation of body temperature, and sensory perception. The skin comprises multiple layers, each with specific roles, and it accounts for about 15% of a person's total body weight. This vital organ acts as a barrier that prevents pathogens from entering the body while also facilitating the excretion of waste products through sweat. Additionally, skin plays a significant role in synthesizing vitamin D when exposed to sunlight, which is essential for various bodily functions. The complexity and extensive coverage of the skin across the entire body substantiate its classification as the largest organ.
