bronchioles small branches of the bronchi; carry air in the lungs
cellular respiration process where cell uses oxygen and nutrients to produce energy
cilia hairlike projections
epiglottis leaf-shpaed structure that closes over the larynx during swallowing
expiration the expulsion of air from the lungs; breathing out air
external respiration exchange of oxygen and carbon dioxide between the lungs and bloodstream
inspiration process of breathing in air
internal respiration exchange of carbon dioxide and oxgen between the tissue cells and the bloodstream
larynx voicebox that lies between the pharynx and trachea
lungs organ of respiration located in the thoracic cavity
nasal cavities hollow spaces in the nasal septum
nasal septum wall of cartilage that divides the nose into cavities
nose projection in center and face; organ for smelling and breathing
pharynx throat, lies behind the nasal cavities
pleura a membrane, or sac, in the lung
respiration process of inspiration and expiration
respiratory system consists of lungs and air passages. takes in oxygen and removes carbon dioxide
sinuses cavities in the skull that surround the nasal area

ventilation process of breathing

sinusitis inflammation of the mucous membrane lining the sinusessymptoms: headache, dizziness, nasal discharge, congestiontreatment: antibiotics, decongestants, and moist inhalations
sleep apnea condition when one stops breathing while asleep, causing decrease in blood oxygen levelstreatment: losing weight and sleeping in different positions
