Vedclass · Answer

(C) In humans,the heart acts as a double pump,where the right side handles deoxygenated blood (pulmonary circulation) and the left side handles oxygenated blood (systemic circulation). This complete separation ensures that oxygenated and deoxygenated blood do not mix. One complete cardiac cycle corresponds to one double circulation. Since the average heart rate in a healthy adult is approximately $72$ to $75$ beats per minute,the heart completes $72$ to $75$ double circulations in one minute. Among the given options,$72$ is the standard value.

How many double circulations are normally completed by the human heart in one minute?
