Te digestive System

NAME:                                                         DATE:  2 June 2016

The food’s journey to the large intestine.

This is all about how the digestive system works. The digestive system is made up of many different parts like the stomach, pancreas

A piece of food starts the digestive tract when it enters your mouth. In your mouth there are these things called salivary gland which along with your mouth and teeth help break up your food which makes it easier for the rest of the journey through the digestive system. Once all of your food has been broken into tiny pieces the tongue the food to be moved into your esophagus.

Once the food has reached the esophagus it gets closer to the stomach. The esophagus is very unique because it pushes the food down by tensing the muscles then relaxing the muscles pushing it down into the stomach.

When the food has reached the stomach the stomachs starts dissolving it into sort of a liquid form from the gastric acid inside your stomach. THis acid is strong enough to dissolve a nail so the stomach produces another layer of mucus every week so it doesn’t destroy itself from the inside out. Once there is enough liquid in the stomach it gets released into the small intestine.

When the food finally reaches the small intestine it is in a watery form so it is easier for the small intestine to collects all of the protein, vitamins, fats and nutrients that help our body to survive.

The pancreas, the liver and the gall bladder produce things called bile which makes life alot easier for the large intestine.

When the food finally reaches the large intestine it is nearly near the end of the digestive system but first it has to harden up so it can come out of the rectum.
