Which outcome occurs when marine mammals dive deeply, causing alveolar collapse?

💡 Explanation

Reduced lung volume decreases oxygen partial pressure; therefore, reducing the efficiency of oxygen uptake via Fick's Law of Diffusion. This occurs because the gas exchange area (surface area) is diminished rather than facilitating more CO2 removal or increased hemoglobin oxygen carrying capacity.
