Chapter 48.2, Problem 2R
Summary Introduction

To review:

The mechanism by which constant and unidirectional flow of air is maintained by birds.

Introduction:

The birds have a unidirectional flow of air which enables them to prevent mixing of pure and impure air. Unlike humans, where pure and impure have a mixing tendency, the lungs of the birds stop mixing and as a result, the partial pressure of oxygen is more in case of birds.
