The defense mechanisms that protect the lungs and describe the effects of polluted air and cigarette smoking on the respiratory system. 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.

Definition Definition Set of metabolic processes and reactions that produce energy from organic substances such as glucose. Cellular respiration takes place in the organism’s cells, where the chemical energy from nutrients or molecules of oxygen is converted into adenosine triphosphate (ATP). Cellular respiration that occurs in the presence of oxygen is called aerobic respiration; in the absence of oxygen, it is called anaerobic respiration.
