Functional Residual Capacity in Lungs — NEET Biology
📚 Practice ConceptFunctional Residual Capacity (FRC): Volume of air that will remain in the lungs after a normal expiration. This includes ERV+RV.
Which of the above statements regarding respiratory volumes and capacities are NOT correct? S1: Inspiratory Capacity (IC) is the sum of Tidal Volume and Inspiratory Reserve Volume, representing the total air a person can inspire after a normal expiration. S2: The volume of air that remains in the lungs even after a normal expiration is known as Functional Residual Capacity (FRC). S3: Vital Capacity (VC) is the maximum volume of air a person can breathe in after a forced expiration, which can also be calculated as Total Lung Capacity minus Expiratory Reserve Volume. S4: A spirometer can be directly used to measure Residual Volume (RV) and Functional Residual Capacity (FRC). S5: The average volume of air that a healthy human can inspire or expire per minute ranges from 6000 to 8000 mL.
