Cardiac Cycle Quiz: How Well You Know?

Cardiac cycle quiz: how well you know? The cardiac cycle involves the functioning of the heart where it contracts and expands and performs one beat to the next. The whole cycle describes what happens when the heart muscles expand to take out blood and relaxes to take in blood. Do you know the role played by different parts of the heart to achieve this process? The quiz below will refresh your memory.
