Document Summary
Rehabilitation sciences 3060a lecture 7: chronic pulmonary dysfunction. Review the anatomy and physiology of the lung: Lung anatomy, volume terminology, and essential physiological elements of matching perfusion to ventilation. Overview of the pathology and what it includes chronic bronchitis and emphysema. The respiratory system can be divided into three main portions: The upper airway consists of nasal cavities, sinuses, pharynx, tonsils, and larynx. Involved in a pathway that will lead to lung. Tries to reduce external environmental factors that should not go into the lung. The lower airway consists of conducting airways to sections dedicated to air exchange. Arrange respiratory anatomy from air entry to location of gas exchange. Distal respiratory unit defined by presence of alveoli. Distal respiratory unit has airway components available for gas exchange. Lung function is comprised of both ventilation and respiration. Ventilation the ability to move air in and out of the lungs via a pressure gradient.
