explanation:-

Residual volume (RV) is the volume of air that remains in the lungs after maximum forceful expiration. In other words, it is the volume of air that cannot be expelled from the lungs. This volume remains unchanged regardless of the lung volume at which expiration was started. Reference values for residual volume are considered to be 1 to 1.2 L, but these values are dependent on many factors including age, gender, height, weight, and physical activity levels.
