6.4.5 Explain the mechanism of ventilation.
Here you need to ensure that you relate the role of the muscles (diaphragm and intercostal muscles) with the changes in volume of the lungs, changes in pressure (relative to the outside atmosphere) and thus the resultant movement of air. Here I explain how these are linked for both inspiration (inhalation), expiration (exhalation) and forced expiration.
Thank you, this was very helpful :D
