Concentration of haemoglobin in blood = 150 g dm^-3.
Volume of oxygen carried by fully saturated haemoglobin = 1.35 cm^3 g^-1.
Resting heart rate = 60 beats per minute.
Volume of blood pumped out of left ventricle every beat = 60 cm^3.
Use these data and information from Figure 8 to calculate the volume of oxygen released to the man's tissues per minute whilst he was at rest.
(Asks for answer in dm^3)
I can't find an official mark scheme answer but according to a quizlet set mine is wrong. I did this:
saturation of Hb with oxygen (which will then be released to tissues)= 38%
Oxygen saturation: (38/100)x1.35=0.513 cm^3g^-1
then finally the volume of oxygen =540x1.35=729cm^3min^-1
The percentage saturation seems quite high but I really don't see how it can be much lower on the graph (attached)
then finally the volume of oxygen =540x 0.513 =277cm^3min^-1
