AURICLES: AURICLES are small and thin walled ,separated from each other by an inter articular septum. they form the anterior portion of heart.
VENTRICLES: are larger, thick walled chambers, also separated by ventricular septum.
VALVES:
right atrium communicates with right ventricle through a valve called tricuspid valve.
left atrium opens into left ventricle through bicuspid valve.
the semilunar valve in pulmonary vein allows the deoxygenated blood to go to lungs and prevent its back flow.
