Definition of respiratory systems in English English dictionary: plural form of respiratory system
respiratory system: The system of organs serving for respiration
respiratory system: the system for taking in oxygen and giving off carbon dioxide; in terrestrial animals this is accomplished by breathing
respiratory system: n. The integrated system of organs involved in the intake and exchange of oxygen and carbon dioxide between an organism and the environment. Organ system involved in respiration. In humans, the diaphragm and, to a lesser extent, the muscles between the ribs generate a pumping action, moving air in and out of the lungs through a system of pipes (conducting airways), divided into upper and lower airway systems. The upper airway system comprises the nasal cavity (see nose), sinuses, and pharynx; the lower airway system consists of the larynx, trachea, bronchi, bronchioles, and alveolar ducts (see pulmonary alveolus). The blood and cardiovascular system can be considered elements of a working respiratory system. See also thoracic cavity
