If expiratory reserve volume is 1100 mL, residual volume is 1200 mL and tidal volume is 500 mL, what shall be the functional residual capacity?

Question

If expiratory reserve volume is 1100 mL, residual volume is 1200 mL and tidal volume is 500 mL, what shall be the functional residual capacity? (A) 1600 mL (B) 2800 mL (C) 2300 mL (D) 1200 mL

Tardigrade Admin · Accepted Answer

Functional residual capacity is the volume of air that remain in the lungs after normal expiration. FRC = RV + ERV =1100+1200=2300 mL .

Q. If expiratory reserve volume is $1100 m L$ , residual volume is $1200 m L$ and tidal volume is $500 m L$ , what shall be the functional residual capacity?

1600 mL

2800 mL

2300 mL

1200 mL

Functional residual capacity is the volume of air that remain in the lungs after normal expiration.
$FRC = R V + ER V$
$= 1100 + 1200 = 2300 m L .$
