The digestive system is a long tube that starts in the mouth and ends in the anus.
- Digestion begins when we chew food in our mouth and mix it with saliva.
- This mixture goes down the oesophagus to the stomach.
- In the stomach, it mixes with gastric juices.
- Next, the mixture passes into the small intestine. Nutrients are absorbed and pass into the blood.
- Undigested food and waste continue on to the large intestine, where water is absorbed and faeces are formed.
- Faeces are excreted through the anus.
