The liver is the largest solid organ inside the body and plays a very important role in the process of digestion by physically regulating it and ensuring release of post digestive nutrients into the system.
Organs that make up the digestive tract are the mouth, esophagus, stomach, small intestine, large intestine-also called the colon-rectum, and anus. Inside these hollow organs is a lining called the mucosa. In the mouth, stomach, and small intestine, the mucosa contains tiny glands that produce juices to help digest food. The digestive tract also contains a layer of smooth muscle that helps break down food and move it along the tract. Two âsolidâ digestive organs, the liver and the pancreas, produce digestive juices that reach the intestine through small tubes called ducts.
