What is the largest organ in the human body?

The largest organ in the human body is indeed the skin. It serves multiple critical functions, including protection, regulation of body temperature, and sensation. The skin acts as a barrier against pathogens, chemicals, and physical injuries. It is also a vital component of the body's ability to regulate temperature through sweating and adjusting blood flow. Moreover, the skin contains sensory receptors that respond to touch, pressure, pain, and temperature, contributing to the body's sense of perception.

Other organs, while essential, do not surpass the skin in size. The heart, although a vital muscular organ responsible for pumping blood, is much smaller than the skin. The liver, despite being one of the largest internal organs and involved in numerous metabolic processes, is still not as expansive as the skin. The kidneys, while crucial for filtering blood and maintaining fluid balance, are comparatively smaller than the skin. Therefore, the skin's extensive surface area makes it the largest organ in the human body.
