The two passive processes required for quiet exhalation.The skeletal muscles required for quiet inhalation.Describe the mechanism of pulmonary ventilation in humans, including a detailed description of the processes of quiet inspiration (inhalation) and quiet expiration (exhalation).Explain the mechanism of ventilation (inspiration and expiration) in humans, including the roles of the structures involved. Include the location, general structure and function of all the following components: ![]() Draw a series of fully-annotated diagrams showing the structure of the respiratory system.Describe the location and function(s) of the major components of the human respiratory system. However, differences in the exact way of measuring this space result in clinically significant different results and, therefore, debate remains about the true value of this measured parameter.Ĭopyright © 2023, StatPearls Publishing LLC.At the end of this unit, you should be able to complete all the following tasks, including answering the guiding questions associated with each task. Indeed, it may serve as a prognostic factor in patients with acute repository distress syndrome (ARDS) who require ventilation. This phenomenon has clinical significance because, both in healthy and impaired lungs, properly calculating and accounting for this non-physiological space is important for the proper respiratory care of ventilated patients. ![]() This is therefore termed anatomical dead space as it serves no respiratory function. ![]() Anatomic dead space is an important phenomenon in respiratory physiology whereby, owing to the fact that upper airways do not function as locations for gas exchange, and because of the tidal nature of ventilation, there is always a fraction of the inspired air that does not perform a physiologic function of exchanging carbon dioxide for oxygen.
