All about Digestion
Digestion is the process of breaking food down into small pieces that your body can absorb and use for energy and growth. It starts in your mouth, where your teeth chew food and saliva begins to break down starch.
Food then travels down the oesophagus to the stomach, where strong acid and enzymes continue the breakdown. The small intestine absorbs nutrients into your blood, and the large intestine takes back water and forms waste that leaves the body.

Frequently asked questions about Digestion
How long does digestion take?
It can take between 24 and 72 hours from eating to leaving the body, depending on what you eat.
Why does my stomach growl?
The muscles of the stomach and intestines contract to move food along, and this can make a rumbling noise, especially when you are hungry.
Do we digest food with our teeth?
Teeth break food into smaller pieces, which makes it easier for enzymes to work on it.
