The lungs expand during inhalation due to the contraction of the diaphragm underneath the lungs. WebbScar tissue in lungs → scar tissue is thicker and less elastic which means that: diffusion distance is increased so rate of diffusion is decreased. Faster ventilation rate to get enough oxygen into the blood and lungs. Lungs can expand and recoil less → Can’t hold as much air which means a reduced tidal volume and forced viral capacity
