16 Buffering Systems in the Blood The regulation of breathing Is controlled not by the amount of oxygen we have circulating in our blood, but Instead by the pH of the blood. Receptors in the brain respond to changes in the pH of the blood, triggering an Increase In the breathing rate If the blood becomes too acidic. Place the following events in order. showing how the body maintains a stable blood pH In response to changes in the carbon dioxide levels in the blood. Assume that a person is exercising and her muscles are releasing carbon dioxide. Rank the options below Increase in breathing rate.exhalling more carbon dioxide Carbonic acid dissociates into water and carbon dioxide. Carbon dioxide combines with water to form carbonic acid There is an increase In carbon dloxide in the blood.
