Question

Identify the correct and incorrect match about the respiratory volume and capacities and mark the correct answer.
(a) Expiratory capacity = Tidal volume + Residual volume
(b) Vital capacity = Total lung capacity – Residual volume
(c) Inspiratory capacity = Total lung capacity – Functional Residual capacity
(d) Total lung capacity = Vital capacity + Functional Residual capacity

• A. (a) - Incorrect, (b) - Correct,
  (c) - Correct, (d) - Incorrect
• B. (a) - Correct, (b) - Correct,
  (c) - Incorrect, (d) - Correct
• C. (a) - Incorrect, (b) - Correct,
  (c) - Incorrect, (d) - Incorrect
• D. (a) - Correct, (b) - Incorrect,
  (c) - Incorrect, (d) - Correct

Answer 1

The correct option is A (a) - Incorrect, (b) - Correct,

(c) - Correct, (d) - Incorrect
(a) Expiratory Capacity (EC) = Tidal Volume (TV) + Expiratory Reserve Volume (ERV)
(b) Vital Capacity (VC) = = Total lung capacity – Residual volume (RV)
(c) Inspiratory capacity (IC) = Total lung capacity – Functional Residual capacity (FRC)
(d) Total lung capacity = Vital capacity (VC) + Residual Volume (RV)

Hence, correction option is a.
