Going From Normal Alveolus To Pulmonary Fibrosis

Pulmonary Fibrosis


Normally, oxygen transfer from the inside of the alveolus to the capillary blood vessel is rapid.  Oxygen moves easily through the membranes and on to the red blood cell.  However, in pulmonary fibrosis, the membrane is thickened making it difficult for the oxygen to attach to the red blood cell.  Consequently, instead of the red blood cell turning red, it remains blue due to lack of oxygen.
