Step 1 : Introduction to the question "What is the only internal organ in humans that can regenerate itself?"
The liver is a large, meaty organ that sits on the right side of the belly. Weighing about 3 pounds, the liver is reddish-brown in color and feels rubbery to the touch. The liver is the only internal organ that can regenerate itself. In fact, you can lose up to 75 percent of your liver, and the remaining parts can regenerate itself into a whole liver again. Hepatocytes are the liver cells that are responsible for the liver's ability to regenerate; they act as stem cells that can re-form liver tissue.
