Flashcards Airway Anatomy EMT | Quizlet

Functions of the respiratory system

delivers O2 to lungs, gets rid of CO2, airflow through the larynx creates speech, converts O2 from inhaled air to blood delivery

Upper airway

nose, pharynx, larynx,

Lower airway

trachea, bronchi, bronchioles, alveoli

Nose

warms, moistens, filters air (inhalation, inspiration)

Tonsils

help protect from infection that enters through the mouth or nose

3 tonsils

nasopharyngeal, palatine, lingual

Palatine tonsils

back of the mouth

nasopharyngeal tonsils

behind the nose, roof of mouth

lingual tonsils

root of tongue

Sinuses

air filled cavities lined with mucous membranes

function of sinuses

make skull bones lighter, produce sound, produce mucous to lubricate tissue of the nasal cavity

sinuses locations

frontal sinuses, sphenoid sinuses, ethmoid sinuses, maxillary sinuses

frontal sinuses

in the frontal bone above the eyebrows

sphenoid sinuses

in the sphenoid bone behind the eyes and under the pituitary gland

maxillary sinuses

Largest! under the eyes

ethmoid sinuses

in ethmoid bone between the nose and the eyes

the roof of the mouth is made up of

hard palate and soft palate

the tongue is connected to the mandible by

hyoid bone with muscle and ligaments

what is the most common airway obstruction

the tongue

the pharynx is also known as

the throat

what are the 3 parts of the pharynx

nasopharynx, oropharynx, laryngopharynx

nasopharynx

posterior to nasal cavity for transport of air

oropharynx

posterior to oral cavity, has functions in the respiratory and digestive system

laryngopharynx

shared by the respiratory and the digestive system

larynx is also known as the

voice box

how many different cartilage support the larynx? which is the largest?

9, the thyroid cartilage

what is the thyroid cartilage also known as

Adam's apple

4 structures of the larynx

epiglottis, thyroid cartilage, glottic opening, cricoid cartilage

cricoid cartilage divides

upper and lower airway

the trachea is also called

windpipe

the trachea is anterior to the

esophagus

the trachea bifurcates at the

carina

3 types of bronchi

primary, secondary, tertiary

Which mainstream of bronchi is shorter, straighter, and wider making it more prone to obstruction

the right

bronchi branch into the

bronchioles/ bronchiole tree

where does gas exchange occur

alveoli

How many lobes are in the left lung

2 lobes

How many lobes are in the right lung

3 lobes
