Question
mework Saved He Regulation of Breathing Regulation of breathing is controlled not by the amount of oxygen circulating in the blood but by blood pH. When the blood becomes too acidic, receptors in the brain respond to changes in blood pH and increase breathing rate. Order the following events to show hov the body maintains stable blood pH when blood carbon dioxide levels change. Assume a person is exercising and her muscles are releasing carbon dioxide. Increase in breathing rate, exhaling more carbon dioxide Carbonic acid dissociates forming bicarbonate and hydrogen ions Carbonic acid dissociates into water and carbon dioxide Receptors in the brain detect an increase in acidity of blood Carbon dioxide combines with water to form carbonic acid. pH of the blood increases (become more basic) Increase in carbon dioxide in the blood. pH decreases in the blood (it becomes more acidic)Explanation / Answer
The order of events to show how the body maintains stable blood pH when blood carbondioxide levels change when a person is exercising and her muscles are releasing carbondioxide is given below,
