2.1 What do you mean by electric energy?

Electrical energy is the power an atom's charged particles have to cause an action or move an object. The movement of electrons from one atom to another is what results in electrical energy. There are two types of electricity: static and current.

-         Static electricity.- It doesn't move from one place to another and stays in the place it was created.

·    Circulatory system

 

-          The circulatory system moves blood around our body. The main organs are: the heart, arteries and veins. Blood is made up of plasma, red blood cells, white blood cells and platelets.

   The  circulatory system transport nutrients and oxygen to every cell in your body.

-       The circulatory system consists  of heart and blood vessels.

-     

·        Respiratory system

 

       The respiratory system alow us to breath. We breath oxygen through our  nose and expel carbon dioxide through our mouth.

    The main organs are: nose, mouth and lungs. This is the process:

1º.-  When you breathe in air enters the body through your mout

2º.- When you breathe out you expel carbon dioxide

 Don´t forget that colds and the flu are caused by viruses and bacteria.

 

·        Excretory  system

-       The excretory system is made up of the urinary system and sweat glands. 

      The urinary system

1º.- The kidneys separate water and minerals from the blood to produce urine.

2º.- The bladder releases urine through the urethra.

  

·       Digestive system

                  

-         The digestive system help us to digest the food we eat. The main organs are: mouth, stomach and intestine.

 -       The digestive system extracts nutrients from the food you eat.

-       Waste leaves the body through the anus.
