Which statement is correct regarding the epithelia of small intestine and PCT ?

Options

A. Both are having compound columnar epithelia with microvilli
B. Both are having stratified columnar epithelial cells
C. Both are having simple epithelia with microvilli
D. Both are having stratified epithelia but cells are of different shapes.

Answer

To determine the correct statement regarding the epithelia of the small intestine and the proximal convoluted tubule (PCT), we can analyze the characteristics of the epithelial tissues present in both structures.

### Step-by-Step Solution:

1. **Identify the Type of Epithelium in the Small Intestine:**
- The epithelium of the small intestine is primarily composed of **simple columnar epithelium**. This type of epithelium is specialized for absorption and secretion.

2. **Identify the Type of Epithelium in the Proximal Convoluted Tubule (PCT):**
- The epithelium of the PCT is made up of **simple cuboidal epithelium**. This type of epithelium also plays a role in absorption and secretion but is structured differently compared to the small intestine.

3. **Consider the Presence of Microvilli:**
- Both the small intestine and the PCT have **microvilli** on their epithelial surfaces. Microvilli increase the surface area available for absorption, which is crucial for their functions.

4. **Analyze the Given Options:**
- **Option A:** Both are having compound columnar epithelia with microvilli. (Incorrect)
- **Option B:** Both are having stratified columnar epithelial cells. (Incorrect)
- **Option C:** Both are having simple epithelia with microvilli. (Correct)
- **Option D:** Both are having stratified epithelium but cells are of different shapes. (Incorrect)

5. **Conclusion:**
- The correct statement regarding the epithelia of the small intestine and PCT is **Option C: Both are having simple epithelia with microvilli**.
