The alveoli are primarily composed of thin squamous epithelium.
Alveolar Tissue Composition
The alveoli, tiny air sacs in the lungs responsible for gas exchange, are primarily lined with a specific type of tissue optimized for this function. Here's a breakdown:
-
Thin Squamous Epithelium: According to the reference, "the alveoli possess a lining of thin squamous epithelium that allows for gas exchange." This single-layered tissue facilitates the efficient diffusion of oxygen and carbon dioxide.
- Function: Its thin structure minimizes the distance for gas diffusion.
- Adaptation: The squamous cells are flattened, providing a large surface area for gas exchange.
In summary, the alveoli are predominantly composed of thin squamous epithelium, perfectly suited for its role in gas exchange within the lungs.
