Summary Introduction
To describe:
The O2 and CO2 diffusion gradient in the lungs and the rest of the body.
Introduction:

Write the mechanism for the transport of CO2 from cellular respiration sites to the lungs.Describe the process including where various steps take place.
explain how basement membranes facillitate gas exchange
The diffusion coefficient of a gas is a constant and is not affected by disease states or treatment options. In contrast the other factors that determine gas diffusion through the respiratory membrane is affected by changes.Name the factors that can cause an increase in the diffusion rate through the respiratory membrane and provide detailed examples of conditions that will cause this increase.
