Vedclass · Answer

(D) The duration of one cardiac cycle in a healthy human heart is approximately $0.8$ seconds.To find the number of cycles completed in $30$ seconds,we divide the total time by the duration of one cycle.Number of cycles = $\frac{	ext{Total time}}{	ext{Duration of one cycle}} = \frac{30 	ext{ s}}{0.8 	ext{ s}} = 37.5$.However,in standard biological calculations for heart rate,if we assume an average heart rate of $72$ beats per minute,then in $30$ seconds,the heart completes $36$ beats.Thus,$36$ double circulations are completed in $30$ seconds.

In the human heart,how many double circulations are completed in $30$ seconds?
