What is the largest organ in the body?

The largest organ in the body is the skin. It covers the entire body and has a massive surface area—roughly 1.5 to 2 square meters—and a weight around 3 to 4 kilograms in an average adult. Beyond protection, skin handles temperature regulation through sweating, provides sensation, helps with vitamin D synthesis, and plays a role in excretion. The liver is the largest internal organ and gland, weighing about 1.4 to 1.6 kilograms and performing major metabolic and detoxification tasks, but it does not exceed the skin in overall size. So, for a general question about the largest organ, skin is the correct answer; if a scenario asked for the largest internal organ, the liver would be described that way.
