Which statement best describes why O 2 and CO 2 can both be exchanged simultaneously at the alveoli and pulmonary capillaries?

Each gas (Oxygen \(O_2\) and Carbon Dioxide \(CO_2\)) diffuses independently down its own partial pressure gradient, allowing for the simultaneous exchange of these gases between the alveoli and the pulmonary capillaries.

B) Blood in the alveoli is high in both O₂and CO_2.
C) Each gas acts independently and diffuses down its own partial pressure gradient.
D) Nitrogen is at a high pressure in both the alveoli and pulmonary capillaries and drives the exchange of O₂and CO₂.
E) Blood in the pulmonary capillaries is high in both O₂and CO_2.
