A trip to the biology fair.

BODY SYSTEMS

 LUNGS 

HEART 

THE HEART IS DIVIDED INTO FOUR DIFFERENT PARTS

 NUTRIENTS

Llamamos nutrientes a todas aquellas sustancias que conseguimos a partir de los alimentos y 
que son necesarias para el correcto funcionamiento del organismo.

Básicamente, los empleamos para obtener energía, 
                       construir nuestra propia materia y 
                       participar en la regulación de algunos procesos del organismo. 




Los nutrientes no son alimentos, sino componentes de los alimentos.

BLOODSTREAM

stomach

small intestine




brain





spinal cord






nerves






organs



1. Listen and read. 
    - Alex and Carla are learning about
      body systems...






2. Read the descriptions below and 
    match them to the pictures. 

    1. We are able to breathe because of 
         this system.
         1-C  Respiratory system. 


    2. This system breaks food down 
         into nutrients. 
         2-B  Digestive system.  

     3. This organ pumps blood 
          around the body. 
          3-E  Heart. 

     4. This system moves blood through 
          the heart and  around the body. 
          4-D  Circulatory system. 

     5. The brain, spinal cord and nerves make up 
          this system. 
          5-A  Nervous system.

Body systems. PB. pages 6 and 7.

1. Name three different body systems.

                 1. The circulatory system.
                 2. The digestive system. 
                 3. The respiratory system. 

    2. What are the functions of these 
                 body systems?  

   Which system helps us digest our food?
    -Digestive system.
   Which system helps us breathe?
    -Respiratory system.
   Which system takes blood around the body? 
     -Circulatory system. 




What is the function of the digestive system?
The digestive system helps us digest our body.
The digestive system breaks down food into 
                                   nutrients.

What is the function of the respiratory system?
The respiratory system helps us breathe.
The respiratory system gets oxygen from the air
                               and expels carbon dioxide.

What is the function of the circulatory system?
The circulatory system takes blood around the 
                                                         body.
The circulatory system takes nutrients and 
                                               oxygen to all parts
                                               of the body.  




 
 3. Name the five senses. 
     Which organs do they use?


      
     

   



Sight.....................eye
Smell....................nose
Hearing.................ear
Taste......................tongue
Touch.....................skin.  

4. Look at Alex and Carla. 
    Which organ is Carla listening to?

Carla´s listening to Alex´s heart.






5. Listen to the song. 
    Which organs do you hear?
    What are the three body systems in the song?


   -The organs I can hear are......
          heart, intestines and lungs. 

 

   -The three body systems in the song are:
        The circulatory, digestive and respiratory
         systems. 


Song:

         Body systems, body systems
         so many systems

                    What do they do?
                    What do they do?






-The heart pumps your blood
  all around your body
  never stopping.

-The circulatory system 
  a transport line to all your cells
  taking nutrients from the small intestine
  oxygen from the lungs
  to all your body parts.





-The circulatory, digestive and respiratory systems
             working together,
             keeping the cells alive,
             helping us survive.
