The organs of the respiratory system are the nose, pharynx, larynx, trachea, bronchi, and lungs. Together these organs send air into the Alveoli; it is a tiny, thin-walled sac of the lungs. Exchange of oxygen and carbon dioxide taken place in alveoli. Carbon dioxide containing blood reach the lungs to expel from the body.
The respiratory system make ensure the oxygen supply to the body cells; furthermore, removes carbon dioxide from the cells. During breathing; the respiratory system filter, warms, and humidifies the air. Sinuses influence the speech or sound production and sense of smell or olfaction.
