Lab 6: Mechanics and Control of Lung Ventilation Respiratory system Functions: GAS EXCHANGE, vocalization, regulation of temperature and pH Internal Respiration: - gas utilization and production in mitochondria and cells External Respiration: gas exchange over respiratory epithelia in lungs or gills Respiratory airways (in order): nasal passages, pharynx, trachea, bronchi and bronchioles and alveoli of the lung. Alveoli – principal gas exchange surface. Walls of alveoli made up of flat think type 1 alveolar cell. Each alveolus is surrounded by associated capillaries. Lungs situated in thorax. Surrounded by thoracic wall and diaphragm. Thin fluid filled space (intrapleural space) separates lung from rib cage and plays vital role in ventilatory movements. Breathing in mammals called tidal ventilation (one direction during inspiration and reverses direction during expiration). Pressure differences between lung and outside drive air into and out of lung Flow = P/R {where R is airway resistance and P is transpulmonary pressure}
