First stage of the process
mouth
Chewing mixes food with saliva
The enzymes in saliva cause
carbohydrate breakdown
Salivary glands
teeth
Salivary glands
tongue

oesophagusLong hollow tube
Carries food, liquid and saliva from the
mouth to the stomach

stomachMuscular hollow bag
Uses acid and enzymes to
breakdown food to allow entry into the
small intestine

Small intestine
Very long folded up tube
Mixes food with enzymes to finish
digestion
Is the area where nutrients
are absorbed

liver
Produces and secrets bile
Bile travels to the small intestine to
help with the breakdown of fat
Is the site of excess glucose
storage

pancreas
Long flat organ behind the stomach
Produces both hormones and enzymes to aid digestion and
absorption
Enzymes travel to the small intestine

Large intestineHome to micro-
organisms that make some
vitamins and amino acids
Is the area of water
absorption

rectumActs as a storage facility
Keeps the faeces until a time when it
can be removed
Found at the end of the
large intestine

Which drink has the least amount of sugar?
![Page 14: My Digestive System HOW DOES THE FOOD YOU EAT GET USED WITHIN THE BODY?](https://reader036.vdocuments.site/reader036/viewer/2022062523/5a4d1adf7f8b9ab0599768c7/html5/thumbnails/14.jpg)
How much sugar is in this drink?We want to know how much is in 330ml
X grams in 100ml = grams in 330ml
X 0.1 = 0.33g
