Question

In a typical heart, if EDV is 120ml of blood and ESV is 50ml of blend, the stroke volume (SV) is

• A. 120 - 50 $=$ 70ml
• B. 120 + 50 $=$ 70ml
• C. 120x50 $=$ 6000ml
• D. 120 +50 $=$ 2.4ml

Answer 1

The correct option is A 120 - 50 $=$ 70ml

The amount of blood moved from the left ventricles of the heart is called stroke volume (SV). SV can be measured by subtracting end-diastolic volume (EDV) with end-systolic volume (ESV) i.e, SV = EDV - ESV, which is 120-50. Result 70ml is the stroke volume.

So, the correct answer is option A.
