Tessellated epithelium is present in : -

Options

A. Ependymal membrane
B. Endothelium
C. Shnederian membrane
D. Alveoli of lungs

Answer

To solve the question about where tessellated epithelium is present, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Term "Tessellated Epithelium":**
- Tessellated epithelium is another name for simple squamous epithelium. It is characterized by its flat, tile-like appearance.

2. **Identify Characteristics:**
- This type of epithelium appears flattened and is sometimes referred to as pavement epithelium due to its resemblance to a pavement. The cells are irregularly shaped and fit closely together.

3. **Function of Tessellated Epithelium:**
- The primary function of tessellated epithelium is to facilitate diffusion. Its thin structure allows for easy passage of substances.

4. **Location of Tessellated Epithelium:**
- Tessellated epithelium is primarily found in areas where rapid diffusion is necessary. Key locations include:
- Blood capillaries in the lungs
- Alveoli of the lungs
- Bowman's capsule in the kidneys

5. **Conclusion:**
- Based on the characteristics and functions of tessellated epithelium, we can conclude that it is present in the alveoli of the lungs, where it plays a crucial role in gas exchange.

### Final Answer:
- Tessellated epithelium is present in the alveoli of the lungs.
