Between 20 and 60 years of age, the RV/TLC ratioA. Increases from 20 to 25 percentB. Increases from 20 to 30 percentC. Increases from 20 to 35 percentD. Increases from 20 to 40 percent

Summary Introduction

Introduction:

Aging causes many effects on the body. Similarly, the lung volumes and capacities are also affected. The total lung capacity generally remains the same.

Explanation

Justification for the correct answer:

Option (C) states that between 20 and 60 years of age, the RV/TLC ratio increases from 20 to 35 percent. Although the overall lung capacity does not change, but the residual volume (RV) and TLC’s ratio are impacted by age. This is because RV increases with age. The ratio increases from 20 to 35 % from 20 to 60 years of age. Hence, option (C) is correct.

Justification for the incorrect answers:

Option (A) states that between 20 and 60 years of age, the RV/TLC ratio increases from 20 to 25 percent. This is incorrect, as with age, the RV/TLC ratio increases from 20 to 35 percent...
