Upper and lower respiratory tracts - Anatomically, what are the divisions of the
respiratory system?
Nasal cavity, nasopharynx, larynx - What is included in the upper respiratory tract?
Extrapulmonary and intrapulmonary - What are the divisions of the lower respiratory
tract?
Trachea and primary bronchi (extrapulmonary bronchi) - What is included in the
extrapulmonary lower respiratory tract?
Intrapulmonary (secondary/tertiary) bronchi
Primary bronchioles
Terminal bronchioles
Respiratory bronchioles
Alveolar ducts
Alveolar sacs (clusters of alveoli) - What is included in the intrapulmonary lower
respiratory tract?
Conducting portion and respiratory portion - Functionally, what are the divisions of the
respiratory system?
Trachea, bronchi, conducting bronchioles, and terminal bronchioles - What is included
in the conducting portion of the lower respiratory system?
Respiratory bronchioles, alveolar ducts, and alveoli - What is included in the respiratory
portion of the lower respiratory system?
Condition the air and conduct/carry the air to the respiratory portion - What is the
function of the conducting portion of the respiratory system?
Site of gaseous exchange between oxygen and carbon dioxide
Exchange occurs through the alveolar wall/septum between pulmonary capillaries and
alveoli - What is the function of the respiratory portion of the respiratory system?
Higher or greater - The smaller the diameter, the _________ the resistance of the
individual structure
Higher - The smaller the diameter, the _________ the pressure of the individual
structure
, Less (due to extensive branching) - The overall resistance of the respiratory portion will
be _________ than the trachea
Pseudostratified ciliated columnar - Identify the type of epithelium labeled A
Goblet cell - Identify the cell labeled B
Upper part of trachea - Identify the part of the respiratory system this slide is from

from
Pseudostratified ciliated columnar - Identify the type of epithelium labeled A
LCT - Identify the type of tissue labeled B

taken from?
Simple squamous - Identify the type of epithelium that the arrow is pointing to in the
image shown
Alveolar duct/alveoli - What part of the respiratory system is this slide taken from?
Lamina propria - What is the LCT just under the PSCC in the trachea called?
BALT tissue (Bronchiole Associated Lymphatic Tissue) - What is the tissue that is under
the PSCC in the trachea that contains lamina propria with high numbers of WBCs
called?
Submucosa - What is the layer of CT denser than lamina propria that contains
seromucous glands called in the trachea?
Towards the bottom - In the trachea, where would you find more glands in the
submucosa, towards the top, or towards the bottom?
Trachealis m. - What is the smooth muscle associated with the trachea called?
Hyaline cartilage - What type of cartilage forms the C-shaped rings in the trachea?
Adventitia - What is the areolar CT that contains adipose and large blood vessels on the
outside of the trachea called?
