Correct answer: C. 72-80
- A. 140-150
- B. 115-125
- C. 72-80
- D. None of these
Explanation
A normal resting adult pulse is commonly about 72 beats/min, and the listed 72-80 beats/min range falls within the usual resting range. Students may choose 115-125 beats/min if they confuse a resting pulse with the faster rate produced during strenuous exercise.

About Cardiac Cycle and Heartbeat
The cardiac cycle describes atrial systole, ventricular systole and diastole, including pressure changes, blood movement and the opening or closing of heart valves. It also covers the conduction pathway from the sinoatrial node through the atrioventricular node, bundle of His and Purkinje fibres, and relates these events to heartbeat sounds.
