Takes in oxygen out of the air
The circulatory system picks up this and drops of this.
Picks up waste and drops of oxygen
There are this many main types of blood cells
Four
The heart has four of these.

The circulatory system helps fight these.
Infections, diseases.
These cells drop off oxygen
Red
Deoxygenated blood (without oxygen) flows into this chamber
We breathe in oxygen and breathe out this waste product of cells.
Carbon dioxide
The circulatory system moves food around your body (not oxygen!)
Food/Nutrients
This type of blood cell guards your body
White

This muscle is the headquarters of your circulatory system.
The heart
These blood cells work hard when you cut yourself
Platelets
The right ventricle pushes blood to this location.
