Question

Quizplus · Accepted Answer

Spirometry is the measurement of the amount of air taken into and expelled from the lungs. Option A is incorrect as bronchoscopy is the examination of the tracheobronchial tree. Option B is partially correct, but spirometry is only a tool used in the diagnosis of respiratory disorders, not the diagnosis itself. Option C refers to the forced vital capacity (FVC), which is a measurement obtained through spirometry. However, this alone does not encompass the full definition of spirometry.
