Explanation:
The amount of blood that leaves the left ventricle of the heart with each contraction is called Stroke volume.
A person has a stroke volume of 80 ml/beat. It means that it is 80 milliliters per beat.
We need to find how many liters would that be.
We know that, 1 litre = 1000 milliliters
1 mL = 0.001 L
To convert 80 mL to litres, we can do it as follows :
80 mL = (80 × 0.001) LL
= 0.08 L
Hence, he stroke volume of a person is 0.08 L/beat.
