Functions of Lower Respiratory Tract n Functions: n Larynx: maintains an open airway, routes food and air appropriately, assists in sound production n Trachea: transports air to and from lungs n Bronchi: branch into lungs n Lungs: transport air to alveoli for gas exchange Copyright of www. makemegenius. com, for more videos , visit us.

Disorders of Respiratory System n Reduced air flow: asthma, emphysema, bronchitis n Infections: pneumonia, tuberculosis, botulism n Lung cancer n Congestive heart failure n Cystic fibrosis Copyright of www. makemegenius. com, for more videos , visit us.

Process of Breathing: Pressure Gradient Inspiration/Expiration: air in/air out n Cycle: n Relaxed state: diaphragm and intercostals muscles relaxed n Inspiration: diaphragm contracts, pulling muscle down, intercostals muscles contract elevating chest wall and expanding volume of chest, lowering pressure in lungs, pulling in air n Expiration: muscles relax, diaphragm resumes dome shape, intercostals muscles allow chest to lower resulting in increase of pressure in chest and expulsion of air n Copyright of www. makemegenius. com, for more videos , visit us.

Measurement of Lung Function n Lung volumes and vital capacity n Tidal volume: volume of air inhaled and exhaled in a single breath n Dead space volume: the air that remains in the airways and does not participate in gas exchange n Vital capacity: the maximal volume that can be exhaled after maximal inhalation n Inspiratory reserve volume: the amount of air that can be inhaled beyond the tidal volume Copyright of www. makemegenius. com, for more videos , visit us.
