Calculate the cardiac of an individual having 70 heart beats/min with a stroke volume of 55 mL.
- A 3750mL
- B 125mL
- C 3850mL
- D None of above
Answer & Solution
Correct Answer
(C) 3850mL
Step-by-step Solution
Detailed explanation
(C) 3850mL,
Cardiac output equals the stroke volume (SV), the volume of blood ejected by the ventricle during each contraction, multiplied by the heart rate (HR), the number of heart beats per minute: CO = SV × HR
The stroke volume, SV = 55 ml and heart rate, HR = 70 beats/min. Therefore, cardiac output=55×70=3850 ml.
