Detailed explanation-1: -So, the correct answer is ‘6750 ml ‘.
Detailed explanation-2: -The average Heart Rate for a person is 75 beats/min and Stroke Volume is 70 ml/beat; with this we get Cardiac Output as 5, 250 ml/Min or we can say 5 L/Min.
Detailed explanation-3: -Thus, the correct answer is ‘70 mL.
Detailed explanation-4: -Expert Answer Cardiac output (CO) can be calculated by multiplying the stroke volume (SV) with the heart rate (HR). Substituting the values of SV and HR in the formula of CO. Thus, it can be concluded that the cardiac output is 5600 mL/min.
Detailed explanation-5: -Cardiac output is the volume of blood being pumped by the heart in a minute. 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.
