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 need to analyze the types of epithelial tissues present in each structure.

### Step-by-Step Solution:

1. **Identify the Epithelium of 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, which is essential for the function of the small intestine.

2. **Identify the Epithelium of 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, particularly in the reabsorption of water, ions, and nutrients from the filtrate.

3. **Examine the Presence of Microvilli:**
- Both the small intestine and the PCT have microvilli on their epithelial cells. Microvilli increase the surface area for absorption, which is crucial for both structures.

4. **Evaluate the Options Given:**
- **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 having stratified epithelia but cells are of different shapes. (Incorrect)

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