The document summarizes the key components and functions of the respiratory system. It describes the major organs involved, including the nose, pharynx, larynx, trachea, bronchi, lungs and alveoli. It also outlines the processes of ventilation, gas exchange, and neural control of breathing. Disorders that can affect the upper and lower respiratory tract are also discussed.
