Histology Of Respiritory System Flashcards
What are the 2 portions of the respiratory system
Conducting - move air in + out
Respiratory - gas exchange
What is the main epithelial lining of the respiratory system
Pseudostratified ciliated columnar epithelium
What is the internal structure of cilia
2 central microtubules with 9 peripheral doublets
Dynein connects microtubules and doublets
What are the layers of mucus
Deep serous
Thick mucus above
What is the function of. Ciliated cells
Cilia beat and move debris up respiratory tract
What is the entrance of the nasal cavity
Nares (nostrils)
What cells line the nasal vestibule (nares) at the cutaneous region
Squamous keritnized epithelium
What cells line the nasal fossa
Ciliated pseudostratified epithelium
What cells are involved in the transitional zone in the nasal fossa
Stratified squamous to stratified cuboidal
What is the function of nasal conchae
Increase surface area
Trap debris
Heat and moisten air
What cells line the soft palate
Stratified squamous epithelium
What is the oropharynx
Space between oral cavity and larynx
What is the function of the larynx
Prevents non air substances from entering the trachea by the epiglottis
Phonation (vocalisation)
What are the 2 types of epithelium lining the larynx
Respiratory epithelium (ciliated pseudostratified)
Stratified squamous
What is the larynx made of
Hyaline cartilage
