Body circulation-
- Left
side of heart pumps oxygen-rich blood to arteries, which carries the
blood to all body parts.
- Blood
from the arties enter the capillaries. In there, oxygen and food move
to cells and the waste gas, carbon dioxide move into blood, blood
enters veins.
- Veins
carry blood with carbon dioxide to the right side of heart. Then it
pumps blood to the lungs.
- In
the lungs blood picks up oxygen and then gives off carbon dioxide.
Then blood moves from the left side of the heart. Then it all starts
over again.

blood is pumped to the lungs by the right ventricle and to the rest of the
body by the left.
