Select the incorrect match w.r.t type of epithelium and its location

Options

A. Transitional epithelium - Ureters are urinary bladder
B. Brush-bordered columnar epithelium - Intestinal mucosa
C. Stratified squamous epithelium - Alveoli of the lungs
D. Brush-bordered cuboidal epithelium - PCT (proximal convoluted tubule)

Answer

To solve the question of selecting the incorrect match regarding the type of epithelium and its location, we will analyze each option provided.

### Step-by-Step Solution:

1. **Understand the Types of Epithelium**:
- Epithelial tissues are classified based on the number of cell layers and the shape of the cells.
- Simple epithelium consists of a single layer of cells, while stratified epithelium consists of multiple layers.
- The shapes of epithelial cells can be squamous (flat), cuboidal (cube-shaped), or columnar (tall and slender).

2. **Evaluate Each Option**:
- **Option A: Transitional epithelium in the ureters and urinary bladder**:
- Transitional epithelium is indeed found in the ureters and urinary bladder. This type of epithelium allows for stretching and is suitable for organs that expand and contract.
- **Conclusion**: This option is correct.

- **Option B: Brush border columnar epithelium in intestinal mucosa**:
- The intestinal mucosa contains columnar epithelial cells, which often have microvilli (brush border) to increase surface area for absorption.
- **Conclusion**: This option is correct.

- **Option C: Stratified squamous epithelium in alveoli of lungs**:
- The alveoli are the sites of gas exchange and are lined with simple squamous epithelium, which is thin to facilitate diffusion. Stratified squamous epithelium would be too thick for this function.
- **Conclusion**: This option is incorrect.

- **Option D: Brush border cuboidal epithelium in proximal convoluted tubule (PCT)**:
- The PCT of the nephron in the kidney contains cuboidal epithelial cells with brush borders to enhance absorption.
- **Conclusion**: This option is correct.

3. **Final Answer**:
- The incorrect match is **Option C: Stratified squamous epithelium in alveoli of lungs**.
