Dr. Lewis Teperman: The Functions of a Healthy Liver

Dr. Lewis Teperman is an associate professor of surgery and vice chairman of surgery at the NYU School of Medicine in

Manhattan. Dr. Teperman specializes in liver transplant surgery, and oversees the medical

center's Organ Transplant Center.

As the body’s largest internal organ, a healthy liver is necessary for good overall health. The liver performs over 500 distinct, vital functions

within the body. It serves as a purifier, breaking down toxins and removing them

through the production of bile. The liver also breaks down food nutrients to produce

proteins and energy, and to store nutrients such as iron for future use. This organ

regulates blood clotting and blood chemical levels. It also supports the immune system

and resists infection by clearing the blood of bacteria.

The liver is the only organ that can regenerate, and it can continue to function even after it has lost three-quarters of its

cells.
