With aging, residual volume (RV) tends to increase due to decreased elastic recoil of the lungs and chest wall, vital capacity (VC) decreases as a result of reduced muscle strength and chest wall compliance, and total lung capacity (TLC) remains relatively constant because the increase in RV compensates for the decrease in VC.
