external respiration is the

exchange of oxygen and carbon dioxide in the lungs

two regions of hte nose

external nose and nasal cavity

roof of the nasal cavity

fethmoid and sphenoid bones

the nasal conchae and mucosa do what during inhalation

filter, heat, and moisten air

the nose does what to inspired air

filters and cleans

the respiratory zone is the

site of gas exchange

what two processes use the circulatory system

transport and internal respiration

major organs of the respiratory system

Nose, nasal cavity, and paranasal sinuses Pharynx Larynx Trachea Bronchi and their branches Lungs and alveoli

the philtrum is

a shower vertical groove inferior to apex

the nose porvides

airway for respiration

the conducting zone includes

all other respiraotry structures

defensins are

antimicrobial peptides

the hard plate is made of

bone

its four processes involve

both respiratory and circulatory systems

pulmonary ventilation aka

breathing

nasal vestibule is where

cavity superior to nostrils

functions of the conducting zone

cleanses, warms and humidifies hair

conducting zone is what

conduits gas exchange sites

function of mucous and serous secretions

contain lysozymes and defensins

what promotes ventilation

diaphragm and other respiratory muscles

what cells secrete mucous

goblet

where is the nasal meatus

groove inferior to each concha

floor of the nasa cavity

hard and soft palate

function of nasal conchae

increase mucosal area and echance air turbulence

the nostrils are bounded

laterlaly by alae

besides the nasal vestibule, the rest of the nasal cavities are

lined with mucous membranes

the nasal conchae protrude

medially from lateral walls

the nose does what to entering air

mositens and warms entering air

cilia in respiraotry mucosa do what

move contaminated mucous posteriorly to the throat

pulmonary ventilation is the

movement of air into and out of the lungs

what type of secretions of respiratory mucosa

mucous and serous seceetions

the soft palete is made of

muscle

nostriles aka

narres

pseudostratified means

not actually stratified, one layer

the respiratory system also functions in

olfaction and speech

ofacotry mucosa contains

olfactory epitheluum

the nose houses

olfactory receptors

transport functio of respiratory system is

oxygen adn carbon dioxide in blood

internal respiration is

oxygen and carbion dioxide exchange between systemic blood vessels and tissue

diaphgragm and other respiratory muscles do what

promote ventilation

type of epithelium in respiratory mucosa

pseduostratified ciliated columnar epithelium

what two processes use the respiraotry system

pulmonary ventilation and external respiration

processes of respiration

pulmonary ventilation, external respiration, transport, internal respiration

during exhalation, the nasal concahe and mucosa do what

reclaim heat and mositure

the nose serves as a

resonating chamber for speech

types of mucous in the nasal cavities

respiraotry and olfactory mucosa

microscopic structures of the respiratory zone

respiratory bronchioles, alveolar ducts, alveoli

the external nose is composed of

root, bridge, dorsum nasi, and apex

the different nasalconchae include

superior, middle, and inferior

major functions of the respiraotry system

supply body with oxygen and dispose of carbon dioxide

what divides the nasal cavity

the nasal spetum

what is in the nasal vestibule and why

vibrissae hairs filter course particles from inspired air

carbon dioxde is a

waste poroduct

where is the nasal cavity

within and posterior to external nose
