The Volume of Blood Ejected from the Ventricles During Each

Question

The volume of blood ejected from the ventricles during each beat is called
A) cardiac output
B) stroke volume
C) systole
D) the cardiac cycle

Accepted Answer

Stroke volume is the amount of blood ejected from one ventricle during a single heartbeat. Cardiac output is the amount of blood pumped out by the heart per minute, which is calculated by multiplying stroke volume by heart rate. Systole refers to the phase of the cardiac cycle when the ventricles contract, while the cardiac cycle refers to the complete sequence of events that occur during one heartbeat.
