Veterinary respiratory system I Flashcards
latin for respiratory system
apparatus respiratorius
protective functions of the airways?
heat
moisten
filter
normal blood pH?
7.4
what parts does the upper respiratory tract consist of?
the nose, paranasal sinuses, pharynx, and larynx
though note that some materials say the larynx belongs to the lower-
what parts does the lower respiratory tract consist of?
the trachea, bronchial tree, and lungs
name the parts of the “conducting system” in order?
nostrils, nasal cavity, paranasal sinuses, nasopharynx, larynx, trachea, and extra- and intrapulmonary bronchi
define surfactant
chemical substance to keep the pulmonary alveoli open
(an amphiphilic lipoprotein complex that greatly reduces the surface tension in the alveoli of the lung keeping them open)
conducting system histologically lined by?
ciliated columnar cells, and a variable proportion of secretory goblet and serous cells
difference between cartilage process and tubercle?
processes are “naked” cartilage, tubercles have soft tissue or other on
adam’s apple in latin
prominentia laryngea
what landmark is found in only some species just rostrally to the main pulmonary bifurcation?
bronchus trachealis in su and ru (and leads to cranial lobe of right lung)
name two parts of os ethmoidale
lamina cribrosa (cribriform palate that separates the ethmoid bone from the cranial cavity)
labyrinthus ethmoidalis
(cellulae ethmoidales in the pig and ruminants)
porous plane relating to olfactory system and the complicated mass behind it (rostrally)
lamina cribrosa
labyrinthus ethmoidalis
In addition to delivering oxygen via air inspiration, the resp. system also participates in what 4 functions?
olfactory system
phonation
body temperature regulation (panting)
blood pH regulation
ciliary beat frequency?
ca 1000 strokes/minute
in eq mucus moves longitudinally at a rate of up to?
20 mm/ minute
what serves as a transitional system?
microscopic bronchioles serve as a transition zone between the conducting (ciliated) system and the gas exchange (alveolar) system
distal bronchioles no longer have
ciliated cells nor goblet cells (but instead have other types of secretory cells)
thoracic part of the trachea, bronchi, and lungs are considered to be?
essentially sterile
External nose
nasus externus
two words for the nose
nasus; rhin
the root of the nose
radix nasi
the dorsal surface of the nose
dorsum nasi
the wings of the nose
alae nasi
