Question

The rate of heart beat in a rabbit is nearly

• A. 92 per minute
• B. 100 per minute
• C. 150 - 300 per minute
• D. None of the above

Answer 1

The correct option is C 150 - 300 per minute

Cardiac output is estimated by heart beat. The amount of blood pumped by the heart per minute is known as cardiac output. Small mammals have high metabolic rates so they faster heart rates than larger-sized mammals. A rabbit at rest normally has a heart rate that ranges from 140 to 180 beats per minute. Stress can cause the heart rate to increase, and the rate in a stressed rabbit can be quite high: well over 300 beats per minute. Therefore the rate of the heartbeat in a rabbit can be ~ 150-300 per minute.

So, the correct answer is option C.
