Vedclass · Answer

(C) Cardiac output is defined as the volume of blood pumped by each ventricle per minute. It is calculated as the product of stroke volume and heart rate.Stroke volume is the amount of blood pumped by the ventricle in one beat,which is the difference between the end-diastolic volume $(EDV)$ and the end-systolic volume $(ESV)$.Given: $EDV = 100 \; mL$,$ESV = 50 \; mL$.Stroke volume = $EDV - ESV = 100 \; mL - 50 \; mL = 50 \; mL$.Cardiac output = $5 \; L = 5000 \; mL$.Formula: $	ext{Cardiac output} = 	ext{Stroke volume} 	imes 	ext{Heart rate}$.$5000 \; mL = 50 \; mL 	imes 	ext{Heart rate}$.Heart rate = $5000 / 50 = 100$ beats per minute.

Which would be the heart rate of a person if the cardiac output is $5 \; L,$ blood volume in the ventricles at the end of diastole is $100 \; mL$ and at the end of ventricular systole is $50 \; mL?$
