Document Summary
Define pulmonary ventilation and outline the mechanism of normal quiet inspiration and expiration with an application to the principle of boyles law. Explain how the intrapulmonary and intrapleural pressures vary during ventilation List the various volumes and capacities and define each of them. Explain the clinical application of forced vital capacity and forced expiratory volume. Describe the role of airway resistance in pulmonary ventilation. Explain the principles of partial pressures (dalton"s law). Explain the principles of gas diffusion and solubility coefficient (henry"s law and. Describe the structure and function of the respiratory membrane. Explain how oxygen is transported in the blood. Interpret changes in the oxygen-hemoglobin dissociation curve with alterations in blood ph, temperature and 2, 3 bpg. Explain how carbon dioxide is transported in blood and what is meant by bohr and. Describe the respiratory system changes associated with acclimatization to a high altitude. Discuss the physiology of the control of respiration.
