Blood minute volume of a 30-year-old woman at rest is 5 l/m. What blood volume is pumped through the pulmonary vessels per minute?

Answer options

1. 1,5 l
2. 3,75 l
3. 2,5 l
4. 5 l
5. 2,0 l

Explanation

Blood minute volume is the amount of blood pumped out by each ventricle in one minute. It is the product of stroke volume and heart rate. Normal value is 5L/ ventricle/minute. If blood minute volume is 5L/m, the volume pumped through the pulmonary vessels (lung vessels) per minute by the right ventricle equals 5L. Same for any given value.
