1. INSTRUCTIONS
1) PREPARING THE ACTIVITY:


Find a suitable text - usually one that is short and cohesive.
In this case we have cut a long text into 5 parts
Then cut each part into short sentences
Laminate the sentences to make them more durable (optional)
Put the sentences inside an envelope mixed, without order.
Number the envelopes from 1 to 5
2) STARTING THE ACTIVITY
Students work in 5 cooperative groups to recreate a text. (5’)
Deliver an envelope to each group of students (5’)
Ask them to put the definitions in order (20’)
Groups proof read and edit their texts before presenting them to the class in spoken
or written form. (3’ each: 15’)
Students compare their texts with the original, attempting to justify the differences
between them. (10’)
2. THE WHOLE TEXT
Digestion is an important body process where the food we eat, gets converted into substances
which can be absorbed by the body.
1 Chewing of the Food
When you are chewing the food, the saliva in the mouth, helps to breaks down the chemicals in the
food to a small extent.
This process makes the food mushy and easier to swallow, the movement of the tongue while
chewing helps to move the food around and the teeth help to chew the food. When the food is
enough mushy, the tongue pushes small amounts of the mashed-up food (called as bolus) inside
the throat.
2 Travelling through the Esophagus Pipe
The tongue pushes the bolus in the opening of the oesophagus, which is a 25 centimetre long and
stretchy pipe. However, at the back of the throat there are two openings, one is the windpipe and
the other is the opening of oesophagus. A small flap called epiglottis, opens the opening of the
oesophagus to pass the food, and makes sure that the food doesn't go down the windpipe. But,
many times if you eat too fast, you can swallow air with the food and get burps!
3 In the Stomach
The food, after passing the oesophagus pipe, enters the stomach, which is like a tilted 'J' shaped
organ.
The stomach performs 3 major functions; it stores the food, it breaks down the mashed-up food
into a liquid mixture and slowly passes this mixture in the small intestine.

The strong muscles in the walls of the stomach and the acidic gastric juices, help to break down the
food, these juices also kill the bacteria present in the food.
4 Passing the Small Intestine
It is a long tube, and an adult's small intestine is around 22 feet long!
The small intestine along with 3 more organs, which are the pancreas, liver and gallbladder further
break down the food to absorb all the essential nutrients like vitamins, minerals, carbs, proteins
and fats in the food. The blood comes to the liver, and the liver filters-out the harmful and waste
substances.
5 Passing the Large Intestine
The digestive system large intestine anatomy is fatter compared to the small intestine, and if
spread out would measure 5 feet.
The large intestine function in digestion is to separate the waste food into solids and liquids, of
which the solid waste comes out as faeces.
