A) expiratory reserved volume
B) inspiratory reserved volume
C) vital capacity
D) inspiratory capacity
Correct Answer: B
Solution :
Volume of air that can be breathed in maximum by forced inspiration above tidal volume or normal inspiration is called Inspiratory Reserve Volume (IRV) While the other options given are inappropriate i.e., the additional volume that can be expired forcibly after a normal expiration is called Expiratory Reserve Volume (ERV), Inspiratory Capacity (1C) is the total volume of air a person can inspire after a normal expiration (it includes TV + IRV) and Vital Capacity (VC) is the maximum value of air a person can breathe in after a forced expiration or the maximum volume of air a person can breathe out after a period of inspiration (this includes TV + IRV + ERV).
