11.2 Respiratory Zone Flashcards
1
Q
respiratory zone is
A
Distal to the terminal bronchioles (aka the respiratory bronchioles and alveoli)
2
Q
Distal most portion of airway
A
Alveolar sacs
3
Q
Respiratory membrane
A
Thinnest separation between outside air and blood
4
Q
Type 1 Alveolar cell are
A
Individual cell of Simple squamous epithelium lining alveolus
5
Q
Tissue lining of capillary
A
Endothelium aka simple squamous epithelium
6
Q
Shared basement membrane
A
In between alveoli and capillaries
7
Q
Respiratory membrane comprised of
A
Type 1 alveoli cell
Basement membrane
Endothelium of capillaries
8
Q
Gas exchange utilizes
A
Oxygen and CO2 concentration gradient
9
Q
Pulmonary edema
A
Fluid accumulating in the space between the basement membrane, leaking into alveoli
10
Q
Type II alveolar cells
A
- produce surfactant (detergent) that coats the surface of alveolus , preventing surface tension (sticking)
- cuboidal in nature
