Question: 1 / 555

What is the largest organ in the human body?

Heart

Brain

Skin

The largest organ in the human body is indeed the skin. It serves vital functions including protection from external elements, regulation of temperature, sensation, and the prevention of water loss. The skin acts as a barrier between internal organs and the outside environment, shielding the body from pathogens, harmful substances, and physical damage.

In terms of surface area and weight, the skin surpasses other organs significantly. For instance, an average adult's skin covers about 20 square feet and can weigh around 8 to 10 pounds. This makes it not only the largest organ but also a crucial component of overall health. Other organs, such as the heart, brain, and liver, while essential, do not match the skin in terms of size.
