Question

If in a person Functional Residual Capacity is 2300 mL, Residual Volume is 1200mL and Inspiratory Capacity is 3500 mL then find out it's Vital Capacity.

( 1 ) 5800 mL
( 2 )7000 mL
( 3 )4600 mL
( 4 )2300 mL​

Answer 1

Answer:

3. 4600

Explanation:

FRC=ERV+RV

ERV=FRC-RV

ERV=2300-1200=1100

VC=ERV+TV+IRV

BUT

IRC=TV+IRV

SO

VC=1100+3500= 4600

Answer 2

Answer:

The Vital Capacity is 4600mL

Explanation:

Vital Capacity = TV+IRV+ERV

ERV = FRC - RV

       = 2300 - 1200 = 1100 mL

VC = IC + ERV

      = 3500 + 1100

      = 4600mL

The vital capacity of lungs id 4600mL.
