Physiological Changes cont…
   Difficulty in respirations due to loss of and lung
    elasticity and enlargement of the
     bronchioles, and decrease in the number
     of aveoli.
   Respiratory muscles atrophy, rib cage
     becomes more rigid, and the diaphragm
     flattens resulting in reduced chest movement
     and ability to inhale and exhale, less effective
     cough, increased work of breathing.
