Question

State the volume of air remaining in the lungs after a normal breathing.

Answer 1

Functional Residual Capacity (FRC): The volume of air which remains in the lungs after a normal expiration is called Functional Residual Capacity. FRC = ERV + RV.

ERV=1000 to 1100 ml

RV = 1100 to 1200 ml

So, FRC = 2100 to 2300 ml

Answer 2

Dear Student,

◆ Answer -

• The volume of air remaining in the lungs after a normal breathing is called as functional residual capacity.

● Functional residual capacity -

• It is volume of air remaining in the lungs at the end of passive expiration.
• It is sum of residual volume and expiratory reserve volume.
• Functional residual capacity of normal human lung is 2300 ml.

Thanks dear. Hope this helps you...
