Animal Tissues: Epithelial
Easybiology
Which epithelial tissue type is specialized for diffusion and lines alveoli of lungs?
Select the correct option:
Solution
Incorrect! Answer:
Simple squamous epithelium
- Simple Squamous Epithelium: Formed by a single, thin layer of flattened cells with irregular boundaries.
- Specialization: Because it is extremely thin, it allows for the rapid passage of substances via diffusion or filtration.
- Distribution: Found in the walls of blood vessels and the alveoli of the lungs, where efficient gas exchange is critical.
- Others:
- Stratified Squamous: Multiple layers for protection (skin).
- Cuboidal: For secretion and absorption (kidney tubules).
- Ciliated Columnar: To move particles/mucus (bronchioles, fallopian tubes).
