As CO2 concentrations rise, it raises levels of carbonic acid in the blood (something CO2 does in aqueous environments; same thing that's bleaching corals in the sea). Our body tracks blood pH and when it dips too low from high CO2, that's when the body knows it needs to breathe. (The above is just going off my memory of my physiology class from years ago. Apologies if I misremembered something.) |
