How is Henry’s law related to the amount of gas that can be exchanged in the alveoli?

• A. Henry’s law states that the small volume of the alveoli will cause an increase the total pressure, allowing gases to be more easily dissolved by the blood.
• B. Henry’s law allows us to predict the relative amount of a gas that will dissolve in the blood when given its partial pressure.
• C. Henry’s law states that molecules will always move towards an area of lower pressure.
• D. Henry’s law states that, in a mixture, the total pressure can be divided into the partial pressures of each gas; this determines how much of each gas will be absorbed by the blood.
