18. The Heart: Chambers Right and left side act as separate pumps
Four chambers
Atria
Receiving chambers
Right atrium receives oxygen poor blood from the body
Left atrium receives oxygen rich blood from the lungs
Ventricles
Discharging chambers
Right ventricle sends oxygen poor blood to the lungs
Left ventricle sends oxygen rich blood to the body
