Question

Which of the following is not correct
(A) Vital capacity = TLC-RV
(B) Total lung capacity = IC+FRC
(C) Functional residual capacity
= ERV+TV
(D) Inspiratory capacity = TV+IRV

Answer 1

Answer:

option Dis not correct answer

Answer 2

Answer:

The option C is not correct.

Explanation:

C. The functional residual capacity (FRC) is the amount/volume of air remaining in the lungs after a normal exhalation. It is the sum of expiratory reserve volume (ERV) and residual volume (RV).

FRC = ERV + RV

A. Vital capacity (VC) is calculated as the total amount of air exhaled after a period of maximum inhalation. It can be calculated as the difference between total lung capacity (TLC) and residual volume (RV).

VC = TLC - RV

B. The total lung capacity (TLC) is the total amount of air that can be held in the lungs. It is the sum of functional residual capacity (FRC) and inspiratory capacity (IC).

TLC = FRC + IC

D. Inspiratory capacity (IC) is the maximum amount of air that can be inspired after a normal expiration. It is the sum of tidal volume (TV) and inspiratory reserve volume (IRV)

IC = TV + IRV
