To explain: The reason for which alveolar air differs in composition from atmospheric air.
Introduction: The process of gas exchange 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 and transported to individual cells of the body and carbon dioxide produced by the cell during cellular respiration is exhaled from the body to the environment.
