18. O2-hemoglobin dissociation curves

what is the curve of partial pressure of O2 in the blood and percentage of hemaglobins oxygenated? can this curve also be a curve of total blood O2 content?

with little partial pressure of O2 in blood, there is a steep increase with oxyhemoglobins, but as the fixed number of hemoglobins in an acute time are occupied with 4 oxygens, it starts to plateau (we call this when the blood is saturated with O2)

yes, it can

what is the additional oxygen content of the blood at rest called and what is it essential for?

venous reserve → used when our body is doing aerobic exercise

what does the graph of CO2 transport look like and what is it analogous with regarding the process of O2?

bicarbonate “transports” CO2 through the blood analogously to the way hemoglobin does
