Location of the epithelial tissue with thin flat cells appearing like packed tiles is

Options

A. inner lining of cheek
B. inner lining of stomach
C. inner lining of Fallopian tubes
D. inner lining of ovary

Explanation

**Step-by-Step Solution:**

1. **Identify the Type of Epithelial Tissue**: The question describes epithelial tissue with thin flat cells that resemble packed tiles. This description matches squamous epithelium, which is known for its flat, thin cells.

2. **Understand the Characteristics of Squamous Epithelium**: Squamous epithelium is also referred to as pavement epithelium due to the way its cells fit closely together, similar to tiles on a floor. This type of epithelium is typically found in areas where diffusion or filtration occurs.

3. **Locate Common Areas for Squamous Epithelium**: Squamous epithelium is commonly found in several locations in the body:
- Alveoli of the lungs
- Terminal bronchioles
- Walls of blood vessels and lymph vessels
- Bowman's capsule in the kidneys
- Coelomic cavity
- Inner lining of the cheek (mucous membrane)

4. **Choose the Correct Location**: Among the options provided, the inner lining of the cheek is a moist surface that is covered by simple squamous epithelium. This makes it the correct answer for the location of the epithelial tissue described in the question.

5. **Eliminate Incorrect Options**:
- The inner lining of the stomach consists of simple cuboidal epithelium.
- The inner lining of the fallopian tube is made up of simple ciliated epithelium.
- The inner lining of the ovary consists of germinal epithelium, which is also cuboidal.

6. **Conclusion**: Based on the characteristics and locations of squamous epithelium, the correct answer is the inner lining of the cheek.

**Final Answer**: The location of the epithelial tissue with thin flat cells appearing like packed tiles is the inner lining of the cheek.
