Nutrients give our cells all the energy they need.
The digestive, repiratory, circulatory and excretory systems
carry out the function of nutrition.

10. THE RESPIRATORY SYSTEM
The respiratory system is in charge of breathing.
Breathing makes two movements:
•First we inhale air and it goes to the lungs.

The respiratory system is made up of:
The nostrils, the pharynx, the larynx, the trachea,
the bronchi, the lungs and the diaphargm.
15. THE EXCRETORY SYSTEM
The excretory system filters waste substances
from the blood. It removes them from the body
through excretion.
16. THE EXCRETORY SYSTEM

from the blood. It removes them from the body
through excretion.
The excretory system is made up of:
17. THE EXCRETORY SYSTEM
The excretory system filters waste substances
from the blood. It removes them from the body
through excretion.
The excretory system is made up of:
•Sweat glands in the skin.
18. THE EXCRETORY SYSTEM
The excretory system filters waste substances
from the blood. It removes them from the body
through excretion.
The excretory system is made up of:
•Sweat glands in the skin.
•The urinary system. This is made up of the kidneys
and the urinary tract.
19. THE CIRCULATORY SYSTEM
The circulatory system transports nutrients and oxygen
to our cells. It is made up of the heart, blood and blood
vessels.
20. THE CIRCULATORY SYSTEM
The circulatory system transports nutrients and oxygen
to our cells. It is made up of the heart, blood and blood
vessels.
The heart is a muscular organ that pumps blood all around
the body.

The heart is a muscular organ that pumps blood all around
the body.
The blood collects oxygen and nutrients. It transports them
to all the cells in the body. It also collects waste substances
and takes them to the sweat glands and the urinary system.

and takes them to the sweat glands and the urinary system.
The blood vessels are tubes through which blood circulates.
There are three types: arteries, veins and capillaries.

THE BLOOD
Blood is a red liquid tissue made up of cells that
float in a liquid called plasma.

There are three types of cells:
•Red blood cells carry oxygen.
• White blood cells remove bacteria and viruses from
the blood.
•Platelets are small fragments of cells that form blood
clots.
27. THE CIRCULATORY SYSTEM
THE HEART
The heart uses rythmic systole and diastole
movements to pump blood all around the body:
