1)Put these organs in the order in which food passes through them… StomachLarge intestine Small intestineoesophagus 2) Food is digested in three parts of the body. Name 2 of them… 3) Digested food is absorbed into the bloodstream in the large intestine. True or False?

Digestive System

Food is pushed down this pipe into the stomach oesophagus stomach The food is squashed by muscular contractions and acid is added. Proteins start to be digested by enzymes

duodenum Small intestine Large intestine Rectum Anus

Gall bladder stores bile In the DUODENUM digestive juices from the pancreas are added and bile which is made in the liver is also added. The ENZYMES help to break the food into smaller particles. The bile helps to NEUTRALIZE the acid from the stomach and also helps to break the fat into little droplets.

Answer these questions in your books Where is food absorbed? What happens in the mouth?

Mini-test Name 3 nutrients that are required for a balanced diet. What is the test for starch? What occurs in the stomach during digestion?

In the large intestine the water that is needed is taken back into the blood. Food is now all digested.

The solid waste or faeces is stored in this part of the large intestine or rectum before passing out the body through the anus.

Anus – the solid waste passes out of the body through this special muscular part

SUMMARY Food is chewed to make digestion easier. The stomach starts to digest the food and makes it into a liquid. The small intestine finishes digesting the food and the tiny dissolved food particles move into the blood. Undigested food passes out through the large intestine.
