Respiratory System Flashcards
encloses the chamber for air inspiration
external nose
cleaning, warming, and humidifying chamber for inspired air
nasal cavity
passageway for food and airs
pharynx
“voice box”; helps keep the airway constantly open, or patent.
larynx
“windpipe”; air-cleaning tube to funnel inspired air to each lung
trachea
are tubes that direct air into the lungs
bronchi
site of gas exchange between the air and the blood
lungs
Upper respiratory tract:
pharynx
external nose
nasal cavity
associated structures
Lower respiratory tract:
trachea
larynx
bronchi
nose consist of
nasal cavity
external nose
identify the structure:
it is the only visible structure
external nose
identify the parts if the nasal cavity:
external openings
nostrils (nares)
identify the parts if the nasal cavity:
openings to pharynx
choanae
identify the parts if the nasal cavity:
anterior portion of the nasal cavity
vestibule
identify the parts if the nasal cavity:
separated the nasal cavity from the oral cavity
hard palate
identify the parts if the nasal cavity:
divides nose into right and left parts
nasal septum
identify the parts if the nasal cavity:
boney ridges in the nasal cavity
conchae
identify the parts if the nasal cavity:
passageway beneath each conchae
meatus
pathophysiology:
inflammation of the mucous membrane of a sinus and it is a viral infection
sinusitis
pathophysiology:
Inflammation of bronchi impairs breathing
bronchitis
pathophysiology:
Destruction of alveolar walls and Loss of alveoli decreases surface area for gas exchange
emphysema
pathophysiology:
characterized by abnormally increased constriction of the trachea and bronchi
asthma
pathophysiology:
rapid and shallow breathing, wheezing, coughing and shortness of breath
asthma
it is the common passageway for air, food and drink
pharynx
