Will the gases continue to diffuse in these directions, or will they stop at some point? For example, the partial pressure of O2 in the alveoli is 104 mmHg and the partial pressure of O2 in the blood in the pulmonary capillaries is 40 mmHg. Will O2 continue to diffuse from the alveoli into the blood until the partial pressure of O2 in the alveoli is 0 mmHg
