Title: Explain the physiological reasons for the lung volumes and capacities that Post by: karastacy on Oct 18, 2011 Explain the physiological reasons for the lung volumes and capacities that changed in the spirogram for this condition with emphysema?
Title: Re: Explain the physiological reasons for the lung volumes and capacities that Post by: bio_man on Oct 20, 2011 A person with emphysema has a loss of intrinsic elastic recoil in the lung tissue as well as increased airway resistance; therefore, while the lungs can expand and fill easily, they can no longer passively recoil and deflate, so that person exhales slowly. A spirogram of a person with restrictive lung disease would have waves with lower amplitude than that of a person with normal lungs.
