In Which Location Would The Partial Pressure Of Oxygen Be The Lowest? The partial pressure of oxygen is high in the alveoli and low in the blood of the pulmonary capillaries. As a result, oxygen diffuses across the respiratory membrane Why is the partial pressure of oxygen lower in the alveoli? The alveolar oxygen partial

What Can A Flatworm Do To Optimize Gas Exchange With Its Environment? Flatworms are small, literally flat worms, which ‘breathe’ through diffusion across the outer membrane ([link]). The flat shape of these organisms increases the surface area for diffusion, ensuring that each cell within the body is close to the outer membrane surface and has
