respiratory system Flashcards
4 pairs of paranasal sinuses
maxillary, ethmoid, sphenoid, frontal
what is the function of the paranasal sinuses
mucosa-lines air cavities that lead into the nasal passages. these paranasal sinuses lengthen the facial bones and act as resonance chambers for speech along with mucus membrane
what is the function of the nasal conchae
increase surface area, warm, moisten air
what bones form the bony part of the nasal septum
perpendicular plate of the ethmoid bone, the vomer and the maxillary crest
the opening of the auditory tube connects nasopharynx to the
middle ear
uvula
prevent food and liquid from going up your nose when you swallow, along with secreting saliva to keep your mouth hydrated
glottis is the entrance to the
larynx
epiglottis
when swallowing, it folds backward to cover the entrance of the larynx so food does not enter the windpipe and lungs
tissue that forms epiglottis
elastic cartilage
what type of cartilage forms the cricoid cartilage
hyaline
what type of cartilage forms the epiglottis
elastic
function of vocal folds
to protect the airway from choking on material in the throat
to regulate the flow of air into our lungs, the production of sounds used for speech
what is brochonstriction
narrowing of airway
what type of tissue lines the trachea
pseudostratified columnar epithelium
what type of cartilage forms the walls of the trachea
hyaline
