A person has a heart rate of 80 beats per minute and a stroke volume of 60 cm3 per beat.
Use the equation:
cardiac output=stroke volume×heart rate \text{cardiac output}=\text{stroke volume}\times\text{heart rate} cardiac output=stroke volume×heart rateWhat is the cardiac output in cm3 min−1\mathrm{cm^3\,min^{-1}}cm3min−1?
