Digestion occurs in every living creature on earth.
1 of 18
Salivary Glands
Secretes/releases saliva, which is a liquid containing enzymes which is a chemical digestion.
2 of 18
Tongue
A muscle that helps to move the food around to teeth to teeth.
3 of 18
Oesophagus
A muscular tube from the back of the mouth to stomach.
4 of 18
Peristalsis
A process that occurs in the Oesophagus and squeezes to help push the food down to the stomach.
5 of 18
Stomach
Causes mechanical breakdown by the muscles. It also adds enzymes (protease) to the food causing chemical breakdown. It also adds hydrochloric acid to make the contents acidic so that the next set of enzymes work and acid helps to kill bacteria.
6 of 18
Liver
Makes bile, which is stored in the gall bladder.
7 of 18
Bile
It is a alkaline chemical (yellow/green), which breaks down large fat molecule into smaller ones. Neutralizes acid so that the next set of enzymes can work.
8 of 18
Pancreas
Releases 3 types of enzymes causing more chemical digestion.
9 of 18
Small intestine
Very long tube with carbohydrase and lipase are released here. It is lined with finger-like projection called villi to absorb nutrients into blood.
10 of 18
Villi
Each one has a blood vessel, which absorbs and digests food with thin walls that is only one cell thick.
11 of 18
Large intestine
It has just fibre, dead cells, bacteria and water, which absorbs water so the poo becomes solid.
12 of 18
Faeces
Poo is released in anus, which is a ring of muscle.
13 of 18
Rectum
Where the faeces is stored.
14 of 18
Enzymes
The enzymes includes: protease, carbohydrate and lipase
15 of 18
Protease
Protease is a protein enzyme. It is released in the stomach, pancreas and small intestine. When it broken down, it turns into amino acid.
16 of 18
Carbohydrase
Carbohydrase is a carbohydrates enzyme. It is released in pancreas and small intestine. When it is broken down, it turns into sugar (glucose)
17 of 18
Lipase
Lipase is a fat enzyme. It is released in the stomach, pancreas and small intestine. When it broken down, it turns into fatty acid (glycerol)
