• trace the flow of air from the nose to the pulmonary alveoli; and • relate the function of any portion of the respiratory tract to its gross and microscopic anatomy. The term respiration has three meanings: (1) ventilation of the lungs (breathing), (2) the exchange of gases between air and blood and between blood and tissue fluid, and (3) the
Overview. The primary function of the respiratory system is supplying oxygen to the blood and expelling waste gases, of which carbon dioxide is the main constituent, from the body. This is achieved through breathing: we inhale oxygen and exhale carbon dioxide.
The anatomical ‘dead space’ consists of the terminal bronchioles, bronchi, trachea and upper airway. Although air passes through this dead space, no gas exchange occurs.
