The liver is one of the body’s largest internal organs, and it plays a critical role in detoxification, metabolism, digestion, and nutrient storage. However, it is not the largest organ overall — that distinction goes to the skin. The liver weighs about 3–4 pounds in an average adult and is located in the upper right abdomen. Its main functions include producing bile to aid digestion, processing drugs and toxins, regulating blood sugar, and storing essential nutrients like iron and vitamin A. While undeniably important, the liver’s size is significantly smaller in both area and weight compared to the skin. Confusing the two may stem from the liver’s vital metabolic functions, but when considering size, the skin is the largest organ by far.
