You tell me that is why I'm asking
Well, between the right ventricle and the pulmonary arteries is an atrioventricular valve called the PULMONARY VALVE . Between the left ventricle and the aorta is an atrioventricular valve called the AORTIC VALVE
The partition between the sides of the heart is called the septum.
a but
Blood passes the right atrioventricular valve, called the tricuspid valve, when it leave the right atrium. From there it flows into the right ventricle.
vena cava -> right atrium-> through the right atrioventricular valve -> right ventricle -> through the Plumonary semi-lunar valve -> Plumonary trunk -> out the pulmonary artery -> lungs -> pulmonary veins -> left artrium -> through the left atrioventricular valve -> left ventricle -> through the aortic valve -> aorta -CB
right atrioventricular valve
pulmonary artery
They are both found in the right side of the heart and deal with transferring deoxygenated blood to the lungs. The valves themselves include three flaps.
Pulmonary Artery
The right ventricle
Blood passes through the right atrium to the right atrioventricular valve, or "AV valve" for short, into the right ventricle during pulmonary contraction.
