It is also known as the food pipe . 1. From the mouth, the food is pushed into the food pipe (oesophagus) with the action of the tongue. 2. The walls of the oesophagus contract and expand to help the food move down the pipe into the stomach. This expansion and contraction movement is called Peristalsis.
Due to the peristaltic movements of oesophagus, the food enters the stomach where a variety of juices act on it. 1. The food is churned in the stomach for about 3-4 hours where a semi-solid paste is formed. 1. The stomach wall contains three tubular glands in it. The glands present in this wall of stomach secrete gastric juices . 2. The gastric jui...
This partially digested food in the stomach now moves forward into the small intestine . 1. The exit of food from the stomach is regulated by sphincter muscle which releases it in small amounts into the small intestine. 2. The small intestine is the largest part of the alimentary canal. It is called the small intestine because it is very narrow . 3...
Dental Caries or tooth decay is the damage that occurs to teeth which can potentially result in cavities, dental abscesses or even tooth loss .This begins as a result of plaque deposition on teeth. Plaque is a sticky deposit on teeth in which bacterial growth happens fast.This bacterial multiplication can convert the sugars in our food to acid.Enamel is the outermost, hard, white layer of a toothThe aim of this module is to provide students with an introduction to digestive system.

- In the Mouth (or Buccal Cavity) Food is taken into the body (or ingested) through the mouth. The digestion of food starts as soon as we put the food in our mouth.
- In the Oesophagus (or Food Pipe) The oesophagus is a tube (or pipe) which connects the mouth (or buccal cavity) to stomach. Oesophagus is commonly known as food pipe.
- In the Stomach. The stomach is a thick walled bag present on the left side of the abdomen (see Figure 2). It is the widest part of the alimentary canal.
- In the Small Intestine. The small intestine is a very long tube. It is about 7.5 metres long. Though small intestine is very long, it is called small intestine because it is a quite narrow tube.
