Question

place a single word into each sentence to make it correct.

1. (click to select) law states that the amount of gas dissolving in water is determined by its partial pressure.
2. thus, the greater the ( p_{o_2} ) in the alveolar air, the more (click to select) the blood picks up.
3. since blood arriving at the alveolus has a (click to select) ( p_{co_2} ) than air, it releases ( co_2 ) into the air.
4. each gas in a mixture behaves (click to select).
5. the diffusion of one gas does not (click to select) the diffusion of another.

(click to select)
carbon dioxide
daltons
excite
independently
higher
influence
henrys
oxygen

Explanation:

1. Henry's law is a well - known principle in gas - liquid solubility. It specifically relates the amount of gas that can dissolve in a liquid (in this case, water) to its partial pressure.
2. In the context of gas exchange in the lungs, oxygen (\(O_2\)) is the gas that diffuses from the alveolar air (where its partial pressure \(P_{O_2}\) is relevant) into the blood. A higher \(P_{O_2}\) in the alveolar air means more oxygen can be taken up by the blood.
3. For carbon dioxide (\(CO_2\)) exchange, blood arriving at the alveolus has a higher partial pressure of \(CO_2\) (\(P_{CO_2}\)) compared to the alveolar air. According to the principle of gas diffusion (from high to low partial pressure), this causes the blood to release \(CO_2\) into the air.
4. Dalton's law of partial pressures implies that each gas in a mixture behaves independently. This means that the behavior of one gas (e.g., its diffusion, pressure contribution) does not interfere with the behavior of another gas in the mixture in terms of their individual partial pressure - related properties.
5. Building on the concept of independent behavior from Dalton's law, the diffusion of one gas does not influence the diffusion of another gas. Each gas diffuses according to its own partial pressure gradient.
