--- Quote from: sanity_master on May 09, 2010, 03:27:21 pm ---the stroke volume is the volume of blood that is pumped per beat, by the 2 ventricles, thats y we get the cardiac output (the total volume of blood pumped by the heart) per minute. isnt this right?

the answer to the 1st Q> approx. vol. of blood returning to the heart per min. from the left pul. vein only? as it is the left pul. veins only, it would be half of the heart, meaning, half of the blood.......and as the total is 5.6 Liters, the half would be 2.8 liters

the answer would be 2.8 L/min (its in OCT/NOV2001 Q29)......

--- End quote ---

Might be sanity....according to my text book though, stroke volume is the volume pumped out by each ventricle, not by both, and i just double checked on the internet but if the marking scheme says 2.8, i guess i was wrong
