The largest internal organ of the human body is the liver. The liver is a vital organ that has numerous functions, including detoxification, protein synthesis, and production of biochemicals necessary for digestion. It’s also responsible for the breakdown of hemoglobin, insulin, and other hormones, and it plays a crucial role in the metabolism of carbohydrates, fats, and proteins. It is located in the upper right-hand portion of the abdominal cavity, beneath the diaphragm and on top of the stomach, right kidney, and intestines. The liver is reddish-brown in color and has a rubbery texture. It’s notably the only human internal organ capable of natural regeneration of lost tissue.
