at FRC, the pressure in the pleural space is negative

at FRC, the pressure in the lungs is positive

at FRC, the force of the chest wall and lung are at equilibrium

at 70% of the vital capacity, the pressure in the lungs is positive

at RV, the pressure in the lungs is negative

- A. B.

at RV, the pressure in the lungs is negative

Functional Residual Capacity (FRC) is the volume of air present in the lungs at the end of passive expiration.

At FRC, the pressure in the pleural space is negative – This statement is false.

At FRC, the pressure in the lungs is positive – This statement is false.

At FRC, the force of the chest wall and lung are at equilibrium – This statement is true.

At 70% of the vital capacity, the pressure in the lungs is positive – this statement is true.

At RV, the pressure in the lungs is negative – This statement true.
