Assalamoalaikum!!
I want to know what exactly is the dissociation curve..i mean what i understood is...if the blood has more affinity to combine with oxygen it will become 100 % saturated at a very low partial pressure of oxygen...like in the comparison b/w organisms...if the dissociation curve is to the right that means it has more affinity...is it like that??
