Tidal Volume and Minute Ventilation—NEET Biology
📚 Practice ConceptWhat is Tidal volume? Find out the Tidal volume (approximate value) for a healthy human in an hour.
Which of the following statements regarding respiratory volumes and capacities are correct? S1: A healthy human breathes approximately 12-16 times per minute, with a typical Tidal Volume (TV) of 500 mL. S2: The total volume of air inspired or expired per minute by a healthy human ranges from 6000 to 8000 mL. S3: Inspiratory Capacity (IC) is calculated as the sum of Tidal Volume (TV) and Expiratory Reserve Volume (ERV). S4: Residual Volume (RV) represents the volume of air remaining in the lungs after a normal expiration and can be directly measured using a spirometer. S5: Vital Capacity (VC) includes ERV, TV, and IRV, representing the maximum volume of air a person can breathe out after a forced inspiration.
