HOW THE DIGESTIVE SYSTEM WORKS
The Process:
The Process:
1. Digestion: the mouth, esophagus and stomach all help our body digest the food we eat.
2. Absorption: the small intestine absorbs the nutrients from the food. From the small intestine, the nutrients go into the blood.
3. Elimination: the large intestine and rectum transform the undigested food into solids called faeces.
The Parts:
1. Mouth: digestion starts in the mouth. The teeth crush the food and mix it with saliva.
2. Esophagus: the food travels down the esophagus to the stomach.
3. Stomach: in the stomach, the food mixes with gastric juices.
4. Liver: the liver produces a liquid called bile that helps break down the food.
5. Small intestine: the food goes into the small intestine. Here it mixes with bile from the liver. Nutrients are absorbed here and they pass into the blood.
6. Large intestine: the undigested food passes into the large intestine. There it's transformed into faeces.
7. Rectum: finally, the faeces pass through the rectum and leave the body through the anus.
