Respiratory anatomy

L Function: channel air into and out of the nasal cavity

Location: between the nostrils Function: divides the nasal cavity

A Function: filter, warm and moisten air; produce mucus; resonance chamber for speech

M Function: inferior-responsible for the majority of airflow direction, humidification, heating, and filtering of air inhaled through the nose; middle-act as buffers to protect the sinuses from coming in direct contact with pressurized nasal airflow; superior-serve to protect the olfactory bulb

B Subdivision of the Pharynx Function: passageway for air from nasal cavity

C Subdivision of the Pharynx Function: Passageway for food and air

D Subdivision of the Pharynx Function: Passageway for food and air

K Function: air passageway; prevents food from entering lower respiratory tract; voice production

H Function:serves to protect the vocal folds; attachment for several laryngeal muscles

J Function: prevent food from entering lower respiratory system;

F Function:provide attachments for the cricothyroid muscle, posterior cricoarytenoid muscle and lateral cricoarytenoid muscle muscles, cartilages, and ligaments involved in opening and closing the airway and in speech production

I Function: keeping food and drink out of the airway, breathing, and speech

G Function: voice production

E Function: air passageway; filters, warms and moistens air

A Function:serves to protect the vocal folds; attachment for several laryngeal muscles

B Function:provide attachments for the cricothyroid muscle, posterior cricoarytenoid muscle and lateral cricoarytenoid muscle muscles, cartilages, and ligaments involved in opening and closing the airway and in speech production

D Function: prevent food from entering lower respiratory system

C Function: maintain structure of the airway of the trachea

A combination of the vocal folds (vocal cords) and the space in between the folds Function: voice production

B Function: voice production

C Function: keeping food and drink out of the airway, breathing, and speech

D Function: prevent food from entering lower respiratory system

A the most distal segment of the conducting zone Function: passage of air to respiratory zone; secretion of surfactant which reduces surface tension, allowing for bronchioles to expand during inspiration and keeping the bronchioles from collapsing during expiration

B branches no longer contain cartilage or glands in their submucosa Function: passage of air to terminal bronchioles; secretion of surfactant which reduces surface tension, allowing for bronchioles to expand during inspiration and keeping the bronchioles from collapsing during expiration

C Function: passage of air to alveolar ducts

D Function: passage of air to alveoli

E Function: gas exchange with blood- giving oxygen to blood and taking carbon dioxide

F Function: contain groups of alveoli for gas exchange

A branch off the trachea Function:passageway for air

B Branch off the primary bronchi Function:passageway for air

C Branch off secondary bronchi Function:passageway for air

D Branch off tertiary bronchi; branches no longer contain cartilage or glands in their submucosa Function:passageway for air

A Function: house passageways smaller than primary bronchi

B Function: contain uppermost airways

C Function: house passageways smaller than primary bronchi

E Branch off the primary bronchi Function:passageway for air

F Branch off the secondary bronchi Function:passageway for air

G Function: house passageways smaller than primary bronchi

H Function: house passageways smaller than primary bronchi

K Function: house passageways smaller than primary bronchi

I Function: accommodate the heart

J Function: respiration

l Function: house passageways smaller than primary bronchi

M Function: house passageways smaller than primary bronchi

A Function: entry to lungs for airways, blood vessels, and lymph vessels

B Function: passageway for air

C Function: house passageways smaller than primary bronchi

D Function: aids optimal functioning of the lungs during respiration;contains pleural fluid, which allows the pleurae to slide effortlessly against each other during ventilation

E Located next to lungs Function: cover and protect lungs; create pleural cavity which contains pleural fluid, which allows the pleurae to slide effortlessly against each other during ventilation

F Located just deep to thoracic wall Function: cover and protect lungs; create pleural cavity which contains pleural fluid, which allows the pleurae to slide effortlessly against each other during ventilation

G Function: house passageways smaller than primary bronchi

B Branch off tertiary bronchi; branches no longer contain cartilage or glands in their submucosa Function:passageway for air

A Function: gas exchange with blood- giving oxygen to blood and taking carbon dioxide

C Function: Quiet inspiration

D Function: Forceful inspiration and active expiration

A Function:Influences inspiration to shut off (inhibits inspiratory & apneustic centers)

B Function: Prolongs inspiration (stimulates inspiratorycenter); deeper, slower pattern of breath

A Function: lining and secretion of mucus

B Function: contain blood supply; secrete mucus

C Function: maintain opening of airway

D Function: loose connective tissue that binds trachea to surrounding tissues

E Function: secrete mucus

F Function: secrete mucus

G Function: maintain matrix of cartilage

A Function: Move mucus toward throat

C Function: moving vocal folds

B Function: moving vocal folds

A Function: moving vocal folds

What receptors are stimulated more by increased CO2 levels than by decreased O2 levels and stimulate Rhythmicity Area for respiration?

What is the location of the peripheral chemoreceptors of the respiratory system?

What is the location of the central chemoreceptors of the respiratory system?

A Function: gas exchange

B Function: produce surfactant that keeps alveoli from collapsing and sticking together by decreasing surface tension

A Function: provide structure to external nose

B Part of ethmoid bone Function: create channel for middle nasal meatus

C Part of ethmoid bone Function: separate the two sides of the nose (septum)

D part of maxilla Function: create channel for inferior nasal meatus

E Function: provide part of nasal septum and hard palate

B Function: decreasing weight of skull; increasing resonance of voice; humidifying and warming air

A Function: decreasing weight of skull; increasing resonance of voice; humidifying and warming air

C Function: decreasing weight of skull; increasing resonance of voice; humidifying and warming air

D Function: decreasing weight of skull; increasing resonance of voice; humidifying and warming air
