To solve this problem, we need to determine the heart rate given the cardiac output, end-diastolic volume, and end-systolic volume.$\newline$Let's break down the information:$\newline \bullet$Cardiac Output (CO) is given as 5 L/min.$\newline \bullet$End-Diastolic Volume (EDV) is 100 mL.$\newline \bullet$End-Systolic Volume (ESV) is 50 mL.$\newline$First, we calculate the Stroke Volume (SV):$\newline$SV = EDV - ESV$\newline$SV = 100 mL - 50 mL = 50 mL$\newline$Now, convert the stroke volume to liters:$\newline$SV = 50 mL = 0.05 L$\newline$Next, use the formula for cardiac output:$\newline$CO = SV$\times$Heart Rate (HR)$\newline$Rearrange to find HR:$\newline HR = \frac{CO}{SV} \newline$Substitute the known values:$\newline HR = \frac{5 L/min}{0.05 L} \newline$HR = 100$$ beats per minute$\newline$Therefore, the heart rate of the person is 100 beats per minute.$\newline$This corresponds to Option 3.
