BIOC34H3 Lecture Notes - Carbonic Anhydrase Inhibitor, Electroencephalography, Bronchitis
Document Summary
Bgyc33/cc4 respiratory system study guide, lectures 9-15 (2013) Diaphragm; intercostal muscles; abdominal muscles; chest wall; phrenic nerve. Atmospheric pressure (patm); alveolar pressure (palv); intrapleural pressure (pip) Patm - palv = driving force for air flow in and out of the lungs. Palv - pip = transpulmonary pressure (drives lung expansion) Sample questions: transpulmonary pressure is, patm - pip and the driving force for airflow in and out of the lungs, patm - pip and the driving force for lung expansion. *d) x = lungs expand; y = the number of molecules of air in the lungs decreases: x = lung volume increases; y = the diaphragm relaxes. B: during inspiration, transpulmonary pressure because the decrease in is greater than the decrease in . *a) increases; intrapleural pressure; alveolar pressure: decreases; intrapleural pressure; alveolar pressure, increases; alveolar pressure; intrapleural pressure, decreases; alveolar pressure; intrapleural pressure, increases; atmospheric pressure; intrapleural pressure. Air flow in and out of the lungs.
