1.	What is the approximate duration of a cardiac cycle?(a) 0.1 seconds(b) 72 seconds(c) 1 minute(d) 0.8 secondsI got this question during an online exam.This key question is from Human Circulatory System topic in section Body Fluids and Circulation of Biology – Class 11
Answer» The correct choice is (d) 0.8 seconds Explanation: We know that the HEART beats 70-75 times per MINUTE. It beats APPROXIMATELY 72 times per minute. Hence, 72 CARDIAC cycles take place in one minute. Therefore, the duration of one cardiac cycle is 0.8 seconds.
