Which is the most important valve in the heart?

Where does oxygenated blood enters the heart?
Oxygen-rich blood flows from the lungs back into the left atrium (LA), or the left upper chamber of the heart, through four pulmonary veins. Oxygen-rich blood then flows through the mitral valve (MV) into the left ventricle (LV), or the left lower chamber.
How does oxygenated blood enter the heart?
Blood enters the right atrium and passes through the right ventricle. The right ventricle pumps the blood to the lungs where it becomes oxygenated. The oxygenated blood is brought back to the heart by the pulmonary veins which enter the left atrium.
What is a heart ventricle?
ventricle, muscular chamber that pumps blood out of the heart and into the circulatory system. Ventricles occur among some invertebrates. In humans, the ventricles are the two lower chambers of the heart.
