Question

Quizplus · Accepted Answer

Inhaling involves active muscle contractions, primarily of the diaphragm and intercostal muscles, which expand the chest cavity and reduce pressure to draw air in. Exhaling is typically a passive process where these muscles relax, and the elastic recoil of the lungs pushes air out. In asthma, the narrowed airways make this passive process more difficult.
