WebbThe gradients of partial pressure of O 2 and CO 2 drive the gases to diffuse (Fig. 3.3). Inhaled O 2 diffuses from the alveoli into the capillaries, while CO 2 from the blood diffuses into the alveoli. The waste CO 2 in the alveoli is then expired through lung ventilation. Webb13 sep. 2024 · “Compliance” in the context of “pulmonary compliance,” “alveolar compliance,” or “compliance of the alveoli” is the expandability of the lungs or alveoli as calculated by (changes in volume) / (changes in pressure) and may be expressed, for example, in a unit of mL/cm H 2 O. Decreased compliance refers to less inflatability in …
