Your answer is EDS - End Diastole Volume

Keep in mind, there is a period of isovolumic contraction which is the first part of systole and during that phase no blood is actually ejected because the pressure in the ventricle hasn't exceeded the pressure in the aorta (I'm assuming we're talking about the left ventricle)

It is called systole. This is when the ventricles contract and eject blood into the lungs (from the right ventricle) or into the systemic circulation (from left ventricle).

The amount of blood pumped by the left ventricle of the heart during one heartbeat is called?

It is known as stroke volume. Stroke volume (SV) is the volume of blood pumped by the right/left ventricle of the heart in one contraction. The stroke volume is not all of the blood contained in the left ventricle. The heart does not pump all the blood out of the ventricle. Normally, only about two-thirds of the blood in the ventricle is put out with each beat. What blood is actually pumped from the left ventricle is the stroke volume and it, together with the heart rate, determines the cardiac output.


The contraction of the ventricles is referred to as systole and the period of ventricular relaxation is called?

I believe that is called diastole, in contrast to systole, the contraction of the heart muscles.


What is it called when a heart chamber contract?

This is called systole. When the heart chambers relax, it is called distole. I hope that this helps you out!
