1. a) Described two age associated anatomical and two age associated physiological changes in the pulmonary system. b) what are the causes for this age associated changes 1. Reduced rib mobility i. Kyphosis, spondylitis 2. Decreases number of alveoli i. Smoking 1. Increase residual capacity i. Lack of exercise 2. Increase dead space i. Smoking, lack of exercise 2. Describe how the aggregated age related anatomical and physiological changes may make a person vulnerable to the age associated changes described in (1) above Age related changes anatomical changes resulting in less air entering the lungs causing the reduced rib mobility and less alveoli because the lungs don’t work at full capacity. Age related physiological decreases gas exchange, increasing residual capacity and dead space 3. Define below age associated changes and indicate why they are associated with the aged population a. Pneumoconiosis - a disease of the lungs due to inhalation of dust, characterized by inflammation, coughing, and fibrosis. Age associated because it must build up over the years to develop b. Tuberculosis - an infectious bacterial disease characterized by the growth of nodules (tubercles) in the tissues, especially the lungs. Age associated because TB developed with a weak immune system which is associated with the older generation. c. Pulmonary aspiration- lung infection that develops af
