Front

What is the cardiac cycle?

Back

The cardiac cycle is the sequence of events that occurs in the heart during one complete heartbeat, including contraction and relaxation phases.

Front

What are the two main phases of the cardiac cycle?

Back

The two main phases of the cardiac cycle are systole (contraction) and diastole (relaxation).

Front

What is systole?

Back

Systole is the phase of the cardiac cycle when the heart muscle contracts and pumps blood out of the chambers.

Front

What is diastole?

Back

Diastole is the phase of the cardiac cycle when the heart muscle relaxes and the chambers fill with blood.
