Class IX – Science II
TRI-CUSPID VALVE is present between right auricle & right ventricle
BI-CUSPID VALVE is present between left auricle & left ventricle
The Upper 2 chambers of the heart are called AURICLES
These Valves prevent backflow of blood from ventricles to auricles
The lower 2 chambers of the heart are called VENTRICLES
Pulmonary artery carries de-oxygenated blood from right ventricles to lungs.
Blood from different parts of the body open up into the Auricles.
Blood is carried from Ventricles to other parts of the body.
Aorta Carries oxygenated blood from left ventricles to different parts of body.
The pulmonary veins carry oxygenated blood from lungs to left auricle.
