pH of blood
Name: Vivian Huang
I know that the pH of blood must be constant, but why?
What happens if there are too many H+ ions or OH- ions?
The most important thing that happens is that the hemoglobin
molecules (which carry oxygen, in the red blood cells) change
in acidic and basic conditions, to such that the affinity for
oxygen changes. As a result, the blood doesn't pick up enough
oxygen in the lung, or it doesn't deliver enough oxygen to the
rest of the body.
