The document provides an overview of the respiratory system including what it includes, how it works, why we need it, common diseases and illnesses, and ways to protect the respiratory system. The respiratory system includes the lungs, airways, diaphragm, windpipe, throat, mouth, and nasal passages. It works by bringing air into the lungs through the nose and mouth, distributing it through the bronchi and into the blood, and then removing carbon dioxide through exhalation. We need the respiratory system to provide oxygen to all our cells. Common respiratory illnesses include asthma and chronic obstructive pulmonary disease. Ways to protect the respiratory system include not smoking, avoiding air pollution, and regular exercise.
