Question
Chapter 31.4, Problem 4MC
Summary Introduction
To analyze:
The relationship between the pH of the blood and how the brain sets the breathing rate.
Introduction:
Air exhaled by a person has a different gas composition than air absorbed by a person. The capillaries near the alveoli receive oxygen as a result of inhaling. Carbon dioxide is simultaneously transferred from capillaries to alveoli. But not for carbon dioxide, hemoglobin has a stronger affinity. Hemoglobin gains an increased affinity for oxygen when one carbon monoxide molecule attaches to it. To diffuse into the plasma, carbon dioxide becomes bicarbonate ions.
