The human liver (brown) and gallbladder (yellow), illustration. The liver is a large organ in the upper right part of the abdomen. It is involved in digestion, energy storage, blood clotting and breaking down toxins. The liver also produces bile, which is stored in the gallbladder. Bile is released into the intestine via the bile duct, and aids the digestion of fats. (KEYSTONE/SCIENCE PHOTO LIBRARY/?????CUSTOM MEDICAL STOCK PHOTO/SCIENCE PHOTO LIBRARY)
