Explanation:
Detailed explanation-1: -It is equal to the heart rate multiplied by the stroke volume. So if there are 70 beats per minute, and 70 ml blood is ejected with each beat of the heart, the cardiac output is 4900 ml/ minute.
Detailed explanation-2: -The stroke volume is 75 ml if the cardiac output is 6 liters per minute(l/m) and assuming the heart rate is 80 beats per minute(bpm).
Detailed explanation-3: -Thus, the correct answer is 3600 ml.
