Q: Can a person live without a liver?
A: No. The liver stores nutrients that help feed the body when a person has not eaten for a few hours. It also changes other nutrients into more basic elements before sending them to other parts of the body to be used. The liver helps break down sugars, starch, fats, and proteins.
The liver also makes albumin, a protein that helps the body balance fluids. The liver makes clotting factors, which help blood thicken or clot when a person is bleeding. Bile made in the liver is important for digesting food and for other bodily functions.
