conducting zone

respiratory passageways of the respiratory system

respiratory zone

the site of gas exchange in the lungs

the nose

-part of the conducting system of the respiratory system

-provides an airway for respiration

-moistens and warms air

-filters inhaled air

-resonating chamber for speech

-houses olfactory receptors

-contains many sebaceous glands

nasal cavity

-part of conducting system

-includes nostrils (external nares)

-skin covers the entry (nasal vesitbule)

-the proof of skin is that we have nasal hairs (vibrissae)

-also lined with mucosa

-divided by nasal septum

-continuous with nasopharynx

nasal hairs

-provide the first filtering of inhaled air in the conducting system of respiration

olfactory mucosa

-near roof of the nasal cavity

-houses olfactory receptors

-type of mucosa in the nasal cavity

respiratory mucosa

-type of mucosa in the nasal cavity

-lines most of the nasal cavity

-epithelium is pseodostratified ciliated columnar

-gas goblet cells within the epithelium

-cilia move contaminated mucus posteriorly

nasal chonchae

-project medially from the lateral wall of the nasal cavity

-superior, middle, and inferior

the pharynx

-funnel-shaped passageway in the respiratory system

-connects nasal cavity and mouth

-divided into 3 sections by their location (naso, oro, and laryngo)

-type of mucosal lining changes along its length

nasopharynx

-superior to the point where food enters

-part of conducting pathway of the respiratory system

-only an air passageway

-closed during swallowing

-has pharyngeal tonsils

-has opening into the pharyngotympnaic tube (auditory tube)

pharyngeal tonsils

-located on posterior wall of nasopharynx

-destroys entering pathogens

oropharynx

-arch-like entrancway in conducting system of respiratory system

-extend from soft palate to the epiglottis

-has epithelium

-two types of tonsils here

palatine tonsils

-in the oropharynx

-in the lateral walls of the fauces (arch-like entranceway)

lingual tonsils

-in the oropharynx

-covers the posterior surface of the tongue

laryngopharynx

-passageway for both food and air

-has epithelium

-continuous with the esophagus and larynx

larynx

-voice production

-provides an open airway

-routes air and food into the proper channels

-superior opening is closed during swallowing

-and open during breathing

vocal folds

-type of vocal ligament of the larynx

-true vocal cords

-act in sound production

vestibular folds

-type of vocal ligament of the larynx

-false vocal cords

-no role in sound production

trachea

-descends into the mediastinum

-C-shaped cartilage rings keep airway open

carina

-marks where trachea divides into two primary bronchi

-has epithelium

pleurae

-double-layered sac surrounding each lung
-2 kinds
-help divide the thoracic cavity

parietal pleura

-type of pleura
-is the outside layer
-"wall"

visceral pleura

-type of pleura
-is the one that lines the organs
-"inside"

pleural cavity

potential space between the visceral and parietal pleurae

primary bronchi

-the pulmonary bronchi
-one to each lung

secondary bronchi

-the lobar bronchi
-three the right lung and 2 to the left

tertiary bronchi

-segmental bronchi
-branch into each bronchopulmonary lung segment

VRG (ventral respiratory group)

-most important respiratory neural control center
-located in reticular formation in the medulla oblongata
-the neurons here generate a respiratory rhythm
