Mouth:
This is where we ingest food.
We do this by using our teeth.
Canine teeth stab and rip food.
incisors cut food.
Our molar grinds the food.
The salivary glands release saliva into the mouth.
saliva starts to break down sugars and lubricates the food.
Oesophagus:
A tube connecting the mouth to the stomach.
Food is pushed down to the stomach by the action of peristalsis.
Stomach
Our stomach churns food into a paste.
Some food gets broken down in the stomach.
Stomach acid kills bacteria.
Duodenum:
This is the first part of the small intestine.
More chemicals are added in from the pancreas and Gall Bladder.
Pancreas:
This adds a chemical into the duodenum to neutralise the stomach acid.
The pancreas also adds more chemicals into the duodenum to break down food.
Why do we have a mouth?
To break do food.
What else does your mouth do?
Breaks down food by chewing
