The liver is found in the right upper quadrant, below the diaphragm and on the belly's right side, notes Healthline. The 3-pound, reddish-brown glandular organ is protected by the rib cage.
The liver plays an important role in the body's metabolism, and its disruption will lead to multiple health problems, warns Healthline. The liver is responsible for filtering the blood that comes from the digestive tract before it is passed to the rest of the body. It is also responsible for metabolizing drugs and detoxifying chemicals. The liver's secretion is called bile, and it is important for breaking up fats so that the small intestine can absorb them more quickly.
