The digestive system of humans contains both a digestive tract and digestive glands. The digestive tract is made up of the foregut, midgut, and hindgut. The foregut includes the mouth, oral cavity, and pharynx. The midgut contains the esophagus, stomach, and small intestines including the duodenum, jejunum and ileum. The hindgut is composed of the large intestines, including the cecum, colon and rectum. The digestive system breaks down food through both mechanical and chemical digestion aided by various digestive glands like the salivary glands, liver, and pancreas.
