Clinical correlatesV. Non respiratory functionsCurrent Lecture-structures that make up the respiratory system-nose-nasal cavity-oral cavity-pharynx-larynx-trachea-bronchial tree-lungs-functions-respiration: gas exchange-replenish O2-eliminate CO2These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.-linked to the cardiovascular system; failure of either organ system leads to rapid cell death-pulmonary embolism: obstruction of a pulmonary artery by a thrombus (blood clot)-blocks flow to the lungs-increases pressure in right ventricle and decreases gas exchange -can cause acute respiratory distress and death-airway obstruction-constriction of the airway from inflammation or asthma-or choking: foreign object blocks some part of the airway-the pharynx, larynx, trachea, or bronchi-non respiratory functions-olfaction: smell-filtering, warming, and moistening air-producing sounds involved in speaking, singing, or nonverbal communication-defending the respiratory system and other tissues from invasion by pathogenic microorganisms-metabolic functions: acid-base balance; balances level of CO2 in blood to maintain
