Pressure – volume curves in the lung is given here. The pressure-volume curves of the total respiratory system (PTR), lungs (PL), and chest wall (Pw) are plotted together with standard lung volumes. Point A indicate which of the following?
Correct Answer: Resting lung volume
Description: Ans. B. Resting lung volumeThe pressure is zero at a lung volume that corresponds to the volume of gas in the lungs at FRC is also known as Resting Respiratory volume/capacity because the opposing forces like the elastic recoil of the lungs and the chest wall are equal and they balance each other at FRC.
