Summary Introduction

To explain: The effects of inhalation of so much dirty air in which the defense mechanisms of respiratory system cannot function effectively.

Introduction: The process of gas exchange that occurs between an organism and its environment is known as respiration. For cellular respiration, most of the animal cells need a continuous oxygen supply. During respiration, oxygen is inhaled from the environment by the animal, and then transported to individual cells of the body. Similarly, carbon dioxide produced by the cell during cellular respiration is exhaled from the body to the environment.
