Solution

The correct option is B 70 ml
Stroke volume (SV) is the amount of blood pumped out of the heart (left ventricle to the body) during each contraction measured in ml/beat (milliliters per beat). Stroke volume is an important determinant of cardiac output, which is the product of stroke volume and heart rate. The stroke volumes for each ventricle are generally equal, both being approximately 70 ml in a healthy 70 kg man.

How many statements are correct?

Stroke volume is the amount of blood the left ventricle pumps out in one cardiac cycle. This is around 70ml. Now, to get the cardiac output, we have to multiply (i)__ with the normal heart rate of (ii)__ /min and we get (iii)__ ml/min. This means that in one minute, each ventricle of a normal heart pumps about (iv)__ litres of blood out.
