Question:

What is the primary function of pulmonary diffusion in the respiratory system?

Answer:

Pulmonary diffusion is the process that occurs in the lungs, allowing for the exchange of gases between the external environment and the bloodstream. During this process, oxygen (O2) is inhaled and diffuses into the bloodstream, while carbon dioxide (CO2), a waste product of metabolism, is removed from the bloodstream and expelled during exhalation.
