Study These Flashcards
A

Non-keratinized stratified squamous

25
What type of tissue protects the vocal cords from mechanical stress
Stratified squamous epithelium
26
What is the function of vocal cords
control airflow and facilitate speaking
27
It includes the trachea, bronchi, bronchioles, and | terminal bronchioles.
Lower Respiratory airway
28
It facilitate oxygen delivery, gas exchange, and immune defense mechanisms.
Lower respiratory airway
29
A tube formed of cartilage and fibromuscular membrane
Trachea
30
What type of tissue is in the lining of the trachea
Pseudostratified ciliated columnar epithelium
31
The primary bronchi, which begin at the bifurcation of the trachea and lead to the right and left lungs.
Extrapulmonary Bronchi
32
Why is it called extrapulmonary bronchi
Because they are | positioned outside the lungs.
33
have C-shaped hyalineHcartilage
Extrapulmonary Bronchi
34
It is narrower and less vertical and gives rise to the two secondary bronchi
Left primary bronchus
35
It is wider and shorter and more vertical, it gives rise to three secondary bronchi;
Right primary bronchus
36
They are secondary and tertiary bronchi
Intrapulmonary bronchi
37
Smaller airways deriving from tertiary bronchi, which continue to branch into terminal bronchioles; no cartilage in their walls
Bronchioles
38
What type of tissue are large bronchioles
Ciliated columnar epithelium
39
What type of tissue are small bronchioles
Ciliated cuboidal epithelium; also has Clara cells
40
The smallest and last of the conducting portion of the respiratory system and they have no gas exchange function.
Terminal Bronchioles
41
It does not have cartilage and has gradually increasing numbers of alveoli.
Respiratory Portion
42
It includes the respiratory bronchioles, alveolar | ducts, alveolar sacs, and alveoli.
Respiratory portion
43
are interrupted | by pouchlike, thin-walled structures
Respiratory Bronchioles
44
What is the type of epithelium of respiratory bronchioles
Cuboidal epithelium
45
Pouchlike, thin-walled structures
Alveoli
46
It arise from respiratory bronchioles
Alveolar ducts
47
Composed of two or more alveoli that share a common opening.
Alveolar sac
48
Thin-walled pouches, which provide the respiratory | surface area for gas exchange.
Alveoli
49
What type of pneumocyte are in the alveoli
Type I and type II
50
Important structure for oxygen and carbon dioxide exchange.
Blood-Air barrier
51
Neighboring alveoli are separated by this and contain elastic connective tissue and may have capillaries within them
Alveolar septa
52
Also known as Type I alveolar cells
Type I pneumocyte
53
What % of type I pneumocyte cover the alveolar surface
95 to 97%
54
What type of tissue are the type 1 penumocyte
Squamous cells
55
These cells cannot divide, but can be regenerated
Type I pneumocyte
56
It can undergo mitosis to regenerate and also can | form type I pneumocytes
Type II penumocytes
57
What % of the alveolar surface is Type II penumocytes
3 to 5%
58
It is also known as dust cells
Alveolar macrophage
59
Where does the dust cells originate from
Bone marrow and blood
