The anatomical human liver as a tie clip! The liver performs a wide variety of important functions, chief among them filtering and processing nutrients directly from the digestive tract, detoxifying chemicals and metabolizing drugs. It's a remarkable organ for its regenerative abilities: "The liver is the only organ that can regenerate itself thus making it possible for one person to donate part of their liver to another person. When a portion of the liver is transplanted, the donor's liver will regenerate back to its original size while the transplanted portion will grow to the appropriate size for the recipient. " (The Canadian Liver Foundation: http://www.liver.ca/liver-health/liver-facts.aspx) This tie clip is an iconic anatomical model of the liver. This little model clearly shows the left and right lobes, the division between them, and the gallbladder.
