respiratory system
inhalation (air in)inspiration
exhalation (air out)expiration
02(oxygen) in air diffuses into bloodexternal respiration
02 in blood diffuses into tissue internal respiration
filters, humidifies and warms airconducting zone
site of gas exchanges (inside the lungs)respiratory zone
region nose just posterior to the external naresnasal cavity
composed of pseudostratified cilited columnar epithelium with goblet cellrespiratory epithelium
open into nasal cavity, lighten the skullparanasal sinuses
3 parts naso, oro and larynphagos pharynx
closes off nasopharynx during swallowing so food doesn’t go into noseuvula
keep food out of airway located posterior to the tounge epiglottis
upper most area, which us directly posterior to the nasal cavity nasopharynx
common passageway of food liquid and airoropharynx
most inferior portion of the pharynx laryngopharynx
the space between the vocal cordsglottis
cartilagenous rings thats keeps the lumen of the trancheaopen and divides in thorax into two main bronchitrancheal cartilage
the center point at the most inferior portion of tranchea carina
two tubes from the tranchea which enters the lungs primary bronchi
structure showing the extensive branching of the bronchitracheobranchial tree
