Sagot :
The thoracic cavity and lung volume increase during inspiration as a result of the diaphragm and external intercostal muscles contracting, which also causes the rib cage to expand and shift outward.
During inspiration, what causes air to enter the lungs?
The diaphragm tightens and pulls down when the lungs inhale. In tandem, the muscles in the space between the ribs tighten and pull upward. By doing so, the thoracic cavity's size and pressure are increased. As a result, the lungs are filled with air.
What occurs to the airflow during inspiration?
The thoracic cavity expands during inspiration as the diaphragm contracts. This lowers the intraalveolar pressure, allowing air to enter the lungs. The lungs fill with air when inspired.
