Gas exchange Speech vocalization Olfaction Ph balance Hormone synthesis Pressure flow for blood and lymph Filter out small clots Valsalva urination deification birth
Why is gas exchange so efficient?
Lipid soluble Exchange surface area is large Diffusion distance is short Pressure gradient is huge Perfusion and ventilation are equal

Branching tubes into each lung
What is boyles law?
Pressure is inversely related to volume
What is Charles law?
Volume of gas is proportional to its temperature.
What is daultons law?
The partial pressures of all the gasses in a system add up to the total pressure
