Squamous epithelium consists of

Options

A. cube - like cells
B. thin flattened cells
C. column like cells
D. ciliated cells

Answer

### Step-by-Step Solution:

1. **Understanding Squamous Epithelium**: Squamous epithelium is a type of epithelial tissue characterized by its thin, flat cells. The cells are arranged in a single layer, which allows for efficient diffusion and filtration.

2. **Identifying Cell Types**: The question asks about the types of cells that make up squamous epithelium. The options provided include:
- Cube cells
- Thin or flattened cells
- Column-like cells
- Ciliated cells

3. **Analyzing the Options**:
- **Cube cells**: These are characteristic of cuboidal epithelium, not squamous.
- **Thin or flattened cells**: This description fits squamous epithelium perfectly.
- **Column-like cells**: These are typical of columnar epithelium, not squamous.
- **Ciliated cells**: These are often found in ciliated epithelium, which is different from squamous.

4. **Conclusion**: Based on the analysis, squamous epithelium consists of thin or flattened cells.

5. **Examples and Functions**: Squamous epithelium is found in areas where rapid diffusion or filtration is necessary, such as in the lungs (alveoli), kidneys (nephrons), and skin. The thinness of the cells allows for easy passage of gases and liquids.

### Final Answer:
Squamous epithelium consists of thin or flattened cells.
