Module 12: Respiratory system (Anatomy 337
UW Madison Exam 2)|83 Verified Q’s and A’s
What is the major organs of the respiratory systems function? - -function
primarily to provide oxygen to body tissues for cellular respiration, remove
the waste product carbon dioxide, and help to maintain acid-base balance.
- Conducting zone of respiratory system involves what?
Major functions?
Structures? - --includes the organs and structures not directly involved in
gas exchange.
-Conditions the air--> filters, warms and cleans the air
-nose and nasal cavities, paranasal sinuses, trachea, bronchi and bronchioles
- The conchae, meatuses, and paranasal sinuses are lined by________.
What is it composed of? - --respiratory epithelium
-composed of pseudostratified ciliated columnar epithelium.
- The epithelium contains goblet cells, what do they produce? - -they
produce mucus to trap debris
- What is the trachea formed of? - -The trachea is formed by 16 to 20
stacked, C-shaped hyaline cartilage pieces connected by dense connective
tissue
- True or False. The trachealis muscle and elastic connective tissue together
form the fibroelastic membrane, a flexible membrane that closes the
posterior surface of the trachea, connecting the C-shaped cartilages. - -
True!! The trachealis muscle and connective tissue form the fibroelastic
membrane, which connects the C-shaped cartilages!
- Regarding the trachea,
What does the fibroelastic membrane allow?
What do the rings of cartilage do? - -- allows the trachea to stretch and
expand slightly during inhalation and exhalation
- the rings of cartilage provide structural support and prevent the trachea
from collapsing.
- Bronchial tree
function?
, Bronchioles further branch into what? Leading where? - -- to provide a
passageway for air to move into and out of each lung
Bronchioles further branch until they become the tiny terminal bronchioles,
which lead to the structures of gas exchange.
- Regarding bronchi, what is the carina and what does it do?
What is its structure? - -The carina is a raised structure containing
specialized nervous tissue that induces violent coughing if a foreign body,
such as food, is present.
-Midline cartilaginous ridge that separates the lumens of primary bronchi
- respiratory zone of respiratory system involves what?
Major functions?
Structures? - --the respiratory zone includes structures directly involved in
gas exchange
-Gas exchange
-respiratory bronchioles, alveolar ducts, alveoli
- Where does the respiratory zone begin? - -The respiratory zone begins
where the terminal bronchioles join a respiratory bronchiole
- Alveolar duct?
Alveolar sac?
Alveolus? - --An alveolar duct is a tube composed of smooth muscle and
connective tissue, which opens into a cluster of alveoli.
-An alveolar sac is a cluster of many individual alveoli that are responsible
for gas exchange
-An alveolus is one of the many small, grape-like sacs that are attached to
the alveolar ducts.
- The alveolar wall consists of three major cell types, what are they?
-
-
- - --type I alveolar cells
-type II alveolar cells
-alveolar macrophages
- Type I alveolar cells - -A type I alveolar cell is a squamous epithelial cell of
the alveoli, These cells are highly permeable to gases.
