Digestive system



We eat food regularly because it provides us the right amount of energy needed in everyday work. If we don't eat food, we will become weaker and weaker.

The food we eat is broken from larger molecules into smaller ones. This process is called digestion. This is the basic function of digestive system.

Functions of digestive system
All the organs of a digestive system are very responsible. Organs of digestive system are mouth, oesophagus, stomach, small intestine, liver, kidney, gallblader, pancreas, spleen, Cecum, Appendix, Ileum, Acending colon, Hypetic Flexure, Duodenum, Gallblader, transverse colon, jejunum, decending colon and Sigmoid Flexure.

1. Mouth
The journey starts all in your mouth where the teeth chop the food into smaller pieces. While that happens the saliva breaks down the food. The sight and smell triggers salivary glands to release saliva. The tongue moves food particles into a bolus that is pushed into your throat.

Sutructures of Mouth
The basic sutructures of mouth are teeth, gums, tongue, tonsils, soft palate, hard palate, upper lips and the lower lips.

2. Pharynx
The epiglottis directs it to the oesophagus and closes the nasopharynx and food will enter the pharynx into the oesophagus.
