What is the alimentary canal?
Bookmark added to your notes. The alimentary canal is a major part of the digestive system. It is a continuous muscular tube which runs through the body and it is around 8 to 10 meters long. It is open at 2 ends, with the mouth at the anterior end and anus at the posterior end. The alimentary canal performs the function of digesting food.
What part of the mouth is the food that enters the alimentary canal?
The mouth is the part where the food enters the alimentary canal. It is the uppermost opening of the alimentary canal and is closed by the upper lip and lower lip. This is where ingestion of food begins.
What is the function of the stomach epithelium?
This pepsinogen helps in the degradation of proteins. The secretion of pepsinogen by the epithelial cells prevents self-digestion of the stomach cells. In addition to the pepsinogen produced by the epithelial cells, the goblet cells also produce mucus that helps prevent self-digestion of the stomach cells .
Which part of the stomach is responsible for preventing food from entering the oesophagus?
The junction where the oesophagus opens into the stomach is protected by a sphincter called the cardiac sphincter. This sphincter prevents swallowed food and acid from entering the oesophagus again by constricting as soon as the food enters the stomach.
How does the tongue help digestion?
The tongue aids digestion by mixing the food with saliva. After mixing the food with the saliva, the tongue and soft palate (roof of the mouth) push the chewed food to the pharynx and down the esophagus. The superior (upper) surface of the tongue consists of various projections known as papillae.

What is the alimentary canal?
The alimentary canal is a continuous passage starting from the mouth and ending at the anus, which carries food through different parts of the digestive system and allows waste to exit the body. The alimentary canal varies widely in organism, but is only seen in organism which are bilaterally symmetrical. Various sections of the alimentary canal contain cells which secrete digestive enzymes, allowing food to be broken down. Other specialized cells allow for the absorption of materials into the body. In human and other highly complex animals, the alimentary canal is organized into specialized tissues and organs. These organs and tissues were derived from the alimentary canal of our earliest ancestors, which likely consisted of a simple tube connecting the mouth and anus.
Which organs are not considered part of the alimentary canal?

During embryonic development, parts of the sphere will fold inward, and connect to the other side, forming the alimentary canal.
What is the function of the large intestine?
The large intestine functions within the alimentary canal to remove excess water and any remaining nutrients from the food being processed.

Digestion starts in the mouth, where saliva begins to break down food. Food then passes through the throat into the esophagus and into the stomach, which secretes acid to aid in digestion.
