2. NUTRITION
NUTRIENTS GIVE TO OUR CELLS ALL ENERGY THAT
THEY NEED
THE DIGESTIVE SYSTEM, THE RESPIRATORY
SYSTEM, THE CIRCULATORY SYSTEM AND THE
EXCRETORY SYSTEM CARRY OUT THE FUNCTION OF
NUTRITION.

3. THE DIGESTIVE SYSTEM
IT HAS TWO PARTS, THE DIGESTIVE TRACT AND THE
DIGESTIVE GLANDS.

4. THE RESPIRATORY SYSTEM
THE RESPIRATORY SYSTEM IS IN CHARGE OF BREATHING.
BREATHING MAKES TWO MOVEMENTS:
FIRST, WE INHALE AIR AND IT GOES INTO THE LUNGS
THEN, WE EXHALE AIR SENDING IT OUT OF THE LUNGS

5. THE EXCRETORY SYSTEM
THE EXCRETORY SYSTEM FILTERS WASTE
SUBSTANCES FROM THE BLOOD. IT REMOVE
THEM THROUGH EXCRETION.
THE EXCRETORY SYSTEM IS MADE UP OF:

6. SWEAT GLANDS

7. THE URINARY SYSTEM

8. THE URINARY SYSTEM
THE URINARY SYSTEM IS MADE UP OF:
THE KIDNEYS AND THE URINARY TRACT.

9. THE CIRCULATORY SYSTEM
THE CIRCULATORY SYSTEM TRANSPORTS NUTRIENTS AND OXYGEN TO OUR CELLS, THERE
ARE THREE TYPES OF BLOOD VESSELS:
THE CIRCULATORY SYSTEMTYPES OF BLOOD VESSELS
ARTERIES
VEINS
CAPILLARIES

10. THE BLOOD

12. THE HEART
THE HEART USES RYTHMIC SYSTOLE AND DIASTOLE MOVEMENTS TO PUMP THE BLOOD
AROUND THE BODY.
FIRST: BLOOD ENTERS IN THE ATRIA.
SECOND:PASSES TO THE VENTRICLES.
THIRD:BLOOD COMES OUT THROUGH THE ARTERIES

13. THE HUMAN CIRCULATION
HUMAN CIRCULATION IS CLOSED AND DOUBLE.
HUMAN CIRCULATION IS CLOSED
BECAUSE THE HEART SEPTUM
SEPARATES THE TWO HALVES OF
THE HEART. PULMONARY CIRCULATION
HUMAN CIRCULATION IS DOUBLE
THE BLOOD FOLLOWS TWO ROUTES
SYSTEMIC CIRCULATION
