Question

In the following functional human lung studies, identify the total lung capacity

I	Inspiratory Capacity (IC)
II	Functional Residual Capacity (FRC)
III	Vital Capacity (VC)
IV	Inspiratory Reserve Volume (IRV)
V	Residual Volume RV)
VI	Expiratory Reserve Volume (ERV)
VII	Tidal Volume (TV)

The correct answer is

• A. IV and VI
• B. I and IV
• C. II and III
• D. III and V

Answer 1

The correct option is D III and V

In this question, they want you to find the formula for calculating the total lung capacity. Total lung capacity is the total volume of air accommodated in the lungs at the end of a forced inspiration. This includes Residual Volume (RV) and Vital Capacity (VC) (1200 + 4800 ml).
