The document summarizes the digestive and respiratory systems. The digestive system breaks down food into nutrients in a multi-step process involving the mouth, esophagus, stomach, liver, pancreas, small intestine and large intestine. The respiratory system takes in oxygen and expels carbon dioxide through a process starting with the nose, pharynx, larynx, trachea and lungs, using the diaphragm during breathing.

1. 6th of Primary
SYSTEMS OF THE NUTRITION

2. DIGESTIVE SYSTEM
In this system, the food is transformed
in nutrients

3. DIGESTIVE SYSTEM
 First, in the mouth, the food mixes with the
salive.
 The TONGUE and the TEETH also help to this
process.

4. DIGESTIVE SYSTEM
 Then, the food goes to the pharynx and the
esophagus.
 It arrives to the STOMACH

5. DIGESTIVE SYSTEM
 In the STOMACH, the food mixes with some
liquids from the liver and the pancreas

6. DIGESTIVE SYSTEM
 After that, the food goes to the large intestine,
that absorbs the nutrients
 The rests goes to the small intestine, and finally
they are expeled by the anus

7. RESPIRATORY SYSTEM
In this system, we take oxygen and expel carbon
dioxide

8. RESPIRATORY SYSTEM
 First, we take air (oxygen).
 This air goes into the nasal cavity. Here, the air is
cleaned and heated.

9. RESPIRATORY SYSTEM
 Then, the air goes into the pharynx.
 After that, it goes to the larynx
 And finally, it arrives to the trachea

10. RESPIRATORY SYSTEM
 The main organs of this system are the LUNGS
 The air enters in the lungs
 We expel carbon dioxide
 The diaphragm moves when we inspire and we
expel air

11. QUESTIONS
 Which system are the lungs in?
 Which system are the intestines in?
 What is the function of the small
intestine?
 What is the function of the digestive
system?
 And the function of the respiratory
system?
 Tell me 3 organs of each system

12. ACTIVITIES
 Label the parts of each system

13. JOURNAL
 Write 3 sentences for each system
