Respiratory System
Respiratory System Consists of an upper respiratory tract(nose to larynx) and a lower respiratory tract(trachea onwards). Conducting portion transports air. -includes the nose,nasal cavity,pharynx,larynx, trachea,and progressively smaller airways,from the primary bronchi to the terminal bronchioles 。 Respiratory portion carries out gas exchange. composed of small airways called respiratory bronchioles and alveolar ducts as well as air sacs called alveoli
