- The main function of the organs of the alimentary canal is to nourish the body by digesting food and absorbing released nutrients. This tube begins at the mouth and terminates at the anus. Between those two points, the canal is modified as the pharynx, esophagus, stomach, and small and large intestines to fit the functional needs of the body.

- The Mouth. Digestion begins in your mouth. Your teeth grind the food you eat and mix it with saliva to form a kind of ball, known as a bolus. During the mixing, an enzyme called salivary amylase starts breaking down carbohydrates.
- The Esophagus. Your esophagus is a flattened muscular tube that connects your mouth to your stomach. As food is swallowed, your esophagus expands. It takes food about three seconds to pass through your esophagus, depending on the texture and consistency.
- The Stomach. Your stomach is a J-shaped muscular pouch, which receives food from your esophagus and sends it to your small intestine. Inside your stomach, food is mixed with enzymes and acid until it becomes a liquid, called chyme.
- The Small Intestine. The small intestine is an approximately 20-foot-long muscular tube, which is divided into three distinct parts: the duodenum, the jejunum, and the ileum.
Your digestive system is a network of organs that help you digest and absorb nutrition from your food. It includes your gastrointestinal (GI) tract and your biliary system. Your GI tract is a series of hollow organs that are all connected to each other, leading from your mouth to your anus.

Nov 2, 2023 · Organs of the digestive system. The digestive tract is also referred to as the alimentary canal. It is a tubular continuum that is segmented into dilated regions. These dilated regions are often separated by thickened regions of the wall that form sphincters. This prevents unintended mixing of the contents in the respective segments.
The human digestive system consists of a long muscular tube and several accessory organs such as the salivary glands, pancreas and gall bladder. It is responsible for food ingestion and digestion, absorption of digestion products and the elimination of undigested materials.
