The main organ under the right rib cage is the liver, which helps clean your blood and makes bile for digesting food.
When you feel the area under your right rib cage, the largest organ you are feeling is your liver. The liver is very important; it cleans your blood, stores energy, and makes bile—a liquid that helps you digest the fat in the foods you eat. In addition to the liver, the gallbladder, which stores bile, is also found right under your rib cage, just below the liver. The diaphragm, a strong muscle that helps you breathe, lies near this area too. Part of your right lung reaches under the ribs as well. However, when people talk about the organ most associated with the right rib cage, they are usually referring to the liver. If you have any concerns about pain or swelling in this area, it’s important to talk with a healthcare provider.
