Pulmonary Diffusion (Medical Definition) | Quick Explainer Video

Pulmonary diffusion refers to the process by which oxygen and carbon dioxide are exchanged between the lungs and the bloodstream. This vital process occurs in the alveoli of the lungs, where oxygen from inhaled air is transferred into the bloodstream and carbon dioxide from the blood is released into the lungs to be exhaled. Pulmonary diffusion is essential for maintaining proper oxygen levels in the body and eliminating carbon dioxide, a waste product of cellular metabolism. Any disruption in this process can lead to respiratory problems and impaired gas exchange, affecting overall health and well-being.
