Question
Chapter 10, Problem 12TY
Summary Introduction
Introduction:
Lungs are basically the primary organ of the biological system, which is the respiratory system. It plays a prime role in providing the site for exchange of gases and respiration. It comprises an elastic, which helps the lungs to rebound after stretching by inhalation.
