Final answer:
The cardiac output is calculated by multiplying the heart rate (HR) by the stroke volume (SV). In this case, the heart rate is 75 beats per minute and the stroke volume is 60 mL per beat. Therefore, the cardiac output is 4.5 liters per minute.
Step-by-step explanation:
The cardiac output is calculated by multiplying the heart rate (HR) by the stroke volume (SV). In this case, the heart rate is given as 75 beats per minute and the stroke volume is given as 60 mL per beat. So, the cardiac output would be:
Cardiac Output = HR × SV
= 75 bpm × 60 mL/beat
= 4500 mL/min
The cardiac output is therefore 4500 mL per minute or 4.5 L per minute.
