The ability of an organ to grow back after injury depends on whether the cells of the organ are regenerative, and how quickly they return to their original size depends on the regenerative capacity of the body’s cells. Liver cells are regenerative cells and have a strong ability to regenerate after injury. After partial removal of the liver, liver cells can divide and regenerate and can recover in a short period of time. The liver can continue to work normally during the recovery period.
But it is important to note that the liver does not recover in exactly the same shape as it was originally. It is only after the liver has been partially removed that the remaining liver tissue regenerates and compensates for the needs of the body.
It is also important to note that some liver diseases can affect the liver’s ability to regenerate. For example, after hepatocellular carcinoma, if the patient has cirrhosis, the liver’s ability to regenerate is reduced, but if the patient does not have other liver disease, the liver can regenerate normally.
