Digestive System

In Year 6 today, we have learnt about how the Digestive System works. We now know that parts link to one another. Mrs Jones helped us understand by using some strange objects to say the least. We used Weetabix, bananas, plastic bags and tights. This is how the stomach works.
First, your teeth chew up the food, this creates a bolus (lump of food). You then  swallow it down your oesophagus leading to your stomach. In the stomach, acid and digestive fluids begin to break down food. Then, your sphinctus opens, allowing smaller pieces of  food to flow through to the small intestine. As this happens, your small intestine allows the nutrients into the blood stream to help make you healthy.  The waste transitions into your large intestine to take the water from the food and use it. Finally, the waste gets pushed into the anus, and flushed out of the body.
