What is the Human Digestive System?

The human alimentary canal is one of the most clearly defined systems in the body. It consists of a long passageway called the digestive tract and other associated glands. This digestive tract is also called the gastrointestinal (GI) tract. The organs of the digestive system contain the pharynx, esophagus, stomach, and small and large intestines. The mouth is also an essential aspect of the digestive system and is the first of the human digestive system parts. The liver, pancreas, and gallbladder are a part of the gastrointestinal tract as well. Enroll now at Tutoroot.
