Respiratory System Anatomy
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
