Lower Digestive Organs

This image shows the lower digestive organs, including liver and stomach (enclosed by the rib cage) and the small and large intestines. After the small intestine absorbs food nutrients, leftover waste passes into the large intestine, where it's worked on by billions of harmless bacteria and mixed with dead cells to form solid feces. The feces are moved into the rectum to await expulsion.
