How do the gas laws (Daltons, Boyles and Henrys)apply to the respiratory processes?

I will be happy to critique your thinking on this.

I know Dalton's Law is the law of partial pressures, Boyle's law is the law for a fixed mass of ideal gas at fixed temperature, the product of pressure and volume is a constant.
And Henry's Law the law where the amount of a given gas dissolved in a volume of liquid is directly proportional to the partial pressure of that gas in equilibrium with that liquid at constant temperature. But I can't find information that relates to the respiratory system!

Here are some hints:
Daltons law: How does CO2 pass from the blood to lungs? How does water vapor come out of the blood to the lungs?

Boyles law: What does the diaphram do the the pressure in the lungs as compared to the outside body pressure?

Henry law: Think on how O2 is absorbed into the capillary from the lung. And, again, on the CO2 escaping.
