Respiratory System: Structure & Function
12
nasal cavity: the interior of the nose: divided by the nasal septum; olfactory receptors located in the superior part.
palate: the nasal cavity is separated from the oral cavity by this partition
pharynx: commonly known as the throat; common passageway for food and air
larynx: voice box, routes air & food into proper channels, inferior to the pharynx
epiglottis: protects the superior opening of the larynx
trachea: the windpipe
bronchi: two main "branches" off the trachea that joins each lung
lungs: occupy the entire thoracic cavity; principle organ of the respiratory system
bronchioles: smaller branches off each bronchi
alveoli: the functional unit of the respiratory system: air sacs, the site of gas exchange
diaphragm:muscle that separates thoracic cavity from abdominal cavity: plays major role in breathing
mouth: secondary function to take in oxygen; does not properly moisten, warm, and filter air before entering lungs
