• A) -13 m/s²
• B) -15 m/s²
• C) 13 m/s²
• D) 15 m/s²
• E) 0 m/s²

Definitions:

Cardiac Cycle

The cardiac cycle is the sequence of events that occurs during one heartbeat, involving the contraction (systole) and relaxation (diastole) of the atria and ventricles to pump blood throughout the body.

Stroke Volume

The volume of blood pumped from the heart's left ventricle per beat.

Cardiac Output

Cardiac Output is the volume of blood the heart pumps through the circulatory system in one minute.

End-Systolic Volume

The volume of blood remaining in each ventricle of the heart after systole, the contraction phase.
