During a thrilling cricket match, a fast bowler's cardiac output needs to be maintained for optimal performance. If the fast bowler has an end-systolic volume (ESV) of 45 mL, an end-diastolic volume (EDV) of 135 mL, and a heart rate of 120 beats per minute, what is the cardiac output in litres per minute (L/min)?

Cardiac Output (CO) can be calculated using the following formula:

CO = Stroke Volume (SV) x Heart Rate (HR)

Stroke Volume (SV) can be calculated by subtracting the End-Systolic Volume (ESV) from the End-Diastolic Volume (EDV):

SV = EDV - ESV

SV = 135 mL - 45 ml  = 90 mL

Finally, calculate the Cardiac Output (CO) by multiplying Stroke Volume (SV) by Heart Rate (HR):

CO = 90 mL/beat x 120 beats/min = 10,800 mL/min = 10.8 L/min
