Respiratory System Flashcards
What portion is responsible for gas exchange?
Respiratory
What are the two portions of the respiratory system?
Conducting and respiratory
What structures make up the conducting portion?
Nasal cavities, nasopharynx, larynx, trachea, bronchi, bronchioles, and terminal bronchioles
What structures make up the respiratory portion?
Respiratory bronchioles, alveolar ducts, alveoli
What are the 5 cell types found in respiratory epithelium?
Ciliated columnar cells, goblet cells, brush cells, basal cells, and small granule cells
What are the two types of basal cells?
Serous cells and DNES cells
Where does hyaline cartilage first appear in the respiratory tract?
Larynx
What is the epiglottis made of?
Elastic cartilage
What are the two surfaces of the epiglottis?
Lingual surface and laryngeal surface
What covers the lingual surface?
Stratified squamous epithelia
What covers the laryngeal surface?
Respiratory epithelia, including pseudostratified ciliated columnar epithelium
What reinforces the trachea?
C shaped rings of hyaline cartilage
What does the trachea divide into?
Two primary bronchi
Where do you no longer see cartilaginous plates?
Around bronchioles (10th generation)
Where are Clara cells found, and what do they do?
Terminal bronchioles; release surfactant, degrade toxins, and regenerate bronchiole epithelium
