Squamous Epithelium Flashcards
1
Q
What is simple squamous epithelium?
A
A single layer of flat cells
2
Q
Where is squamous epithelium found?
A
- walls of small blood vessels (capillaries)
- air sacs of the lungs (alveoli)
3
Q
Explain the benefits of squamous tissue being thin
A
- permits diffusion of substances
- (materials can diffuse out of the capillaries)
- (in lungs; oxygen can diffuse across the alveoli and into the blood)
4
Q
What do the thin, flattened squamous cells promote?
A
Rapid diffusion of gases between the air and the blood vessels underneath the epithelium
