Ventricle -> Pulmonary Valve -> Pulmonary Artery -> Lungs ->
Pulmonary Veins -> Left Atrium -> Mitral Valve -> Left
Ventricle -> Aortic Valve -> Aorta -> Body
CHAMBERS AND FUNCTIONS :
Right Atrium:
Receives deoxygenated blood from body
Right Ventricle:
Pumps blood to lungs
Left Atrium:
Receives oxygenated blood from lungs
Left Ventricle:

Aortic Valve:
Prevents backflow into left ventricle
, MAJOR BLOOD VESSELS :
Superior Vena Cava:
Returns blood from upper body
Inferior Vena Cava:
Returns blood from lower body
Pulmonary Artery:
Carries deoxygenated blood to lungs
