Pulmonary Capacities from Volumes — NEET Biology
📚 Practice ConceptBy adding up a few respiratory volumes described above, one can derive various pulmonary capacities, which can be used in clinical diagnosis.
Which of the following statements regarding the utility and measurements of a spirometer are correct? S1: Spirometer is utilized for the direct measurement of Tidal Volume (TV) during normal respiration. S2: Residual Volume (RV), which is the air remaining in the lungs even after a forcible expiration, can be accurately determined by a spirometer. S3: Inspiratory Capacity (IC) and Expiratory Capacity (EC) can be computed from the volumes obtained directly through spirometry. S4: Functional Residual Capacity (FRC) represents the volume of air remaining in the lungs after a normal expiration and is directly measurable via spirometry. S5: Spirometry provides critical data for the clinical assessment of pulmonary functions, aiding in the diagnosis of various respiratory disorders.
