upper respiratory system consist of

nasal cavity, nostril, oral cavity, pharynx

Lower respiratory system consist of

larynx, R/L main bronchus, trachea, R/L lung, Diaphragm

The conducting zone extends from which structures?

Nasal cavity→Terminal Bronchioles

Conducting Zone is..

the route for incoming and outgoing air

Where does gas exchange first begin?

Respiratory bronchioles

The respiratory zone is where what occurs?

Gas exchange

Respiratory zone extends from which structures?

respiratory bronchioles to alveoli

Which is not a function of the respiratory system?

Nutrient absorption

The nasal cavity is primarily lined with?

pseudo stratified ciliated columnar epithelium

What’s the primary function of cilia in the respiratory tract?

Move mucus toward the pharynx

The oropharynx is lined with:

stratified squamous epithelium ( Non- keratinized )

Goblet cells produce what?

Mucus

The trachea and branch are lined with:

pseudo stratified squamous epithelium

The bronchioles are primarily lined with:

cuboidal epithelium

the alveoli are lined with:

simple squamous epithelium

sinusitis :

Infection of cranial sinuses that drain into nasal cavities, drainage is blocked

The nasal conchae primarily functions to:

Increase surface area and turbulence

the nasal meatuses are:

grooves formed by conchae

the internal nares connect the nasal cavity to the:

nasopharynx

the mucociliary escalator functions to:

remove debris from airwarys

during gas exchange in alveoli:

O2 In, CO2 out

What are the regions of the pharynx

Nasopharynx, oropharynx, laryngopharynx

Function of the pharynx is

a passage way for air + food, resonating chamber, houses the tonsils

Which regions of the pharynx are ONLY for air?

nasopharynx and laryngopharynx

Ottis Media is an infection in what?

Middle Ear

The larynx attaches to what bone:

Hyoid bone

which is not a function of the larynx

passageway for food

The trachea extends from what?

the larynx to T5 Vertebrae

The trachea has 15-20 ____ shaped trachea

C- Shaped

The epiglottis is what type of cartilage

elastic

The main primary bronchi supply….

each lung

The lobar(secondary) bronchus supplies ….

each lobe

the segmental ( tertiary) bronchus supply

each bronchopulmonary segment

The vestibular folds are the

false vocal cords

the vestibular folds are the superior or inferior pair?

superior

the vocal folds are the

true vocal cords

The vocal folds are the superior or inferior pair?

inferior pair

When breathing, vocal cords are …

open to allow air into lungs

When speaking, the vocal cords are …

closed, so air from the lungs presses between them to cause the vibrations that produced sound
