Question

the cardiac output is dependent on ____________. a heart rate b respiration rate c stroke volume d heart rate and stroke volume

Explanation:

Cardiac output is calculated by the formula \(CO = HR\times SV\), where \(CO\) is cardiac output, \(HR\) is heart rate, and \(SV\) is stroke volume. So it depends on both heart rate and stroke volume. Respiration rate is related to the respiratory system, not directly to cardiac output calculation.

Answer:

D. heart rate and stroke volume
