Answer:
(d) Cardiac
Output
(i) The volume of blood
pumped by each ventricle per minute is called the cardiac output. It is 500 mL
or 5 liters in a healthy individual.
It is
determined by multiplying the heart rate with the volume of blood ejected by
each ventricle during each beat, which is called as stroke volume.
Cardiac
output = Heart rate x Stroke volume
=72 beats/min x 0.08 litre/beat = 5.5 litre/min
(iii) Cardiac index
is the minute volume per sq. m. of body surface area. Its normal value is 3.3
lit/min/sq.m.
