Document Summary

Pulmonary system: formed by upper & lower respiratory systems. Upper system: passageways for air, composed by nasal cavity, oral cavity, pharynx (throat) and larynx (line of demarcation) Lower system: composed by the bronchial system and lungs. Diaphragm: how do the following structures figure into respiration: oral cavity, nasal cavity, pharynx, Oral cavity = secondary external opening for the respiratory tract. Nasal cavity = main external opening for the respiratory system. Pharynx = important for swallowing, respiration, and speech, contains nasopharynx oropharynx, laryngopharynx. Larynx = structure in neck, contains vocal folds which create the sound space for speech, passageway for respiration, protects trachea during swallowing in order not to choke, includes hyoid bone and cartilages. Bronchial system = passageways within lower respiratory system, includes trachea, bronchi, bronchioles, and alveoli. 11 cm in length, 2. 5 cm in diameter. Surrounded by 16-20 c- shaped rings of cartilage (closed in front, open in back). Bronchi: in-side lungs, mainstem bronchi split into secondary (lobar) bronchi.
