Which type of tissue is found in PCT and DCT?

Options

A. (1) simple cuboidal brush border and simple squamous
B. (2) simple cuboidal brush border and simple cuboidal ciliated
C. (3) simple cuboidal brush border and simple cuboidal
D. (4) simple cuboidal brush border and simple squamous

Answer

To answer the question regarding the type of tissue found in the Proximal Convoluted Tubule (PCT) and Distal Convoluted Tubule (DCT), we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Structures**:
- The Proximal Convoluted Tubule (PCT) and the Distal Convoluted Tubule (DCT) are components of the nephron in the kidney.

2. **Understand the Function**:
- The PCT is primarily involved in the reabsorption of water, ions, and nutrients from the filtrate back into the blood.
- The DCT also plays a role in the reabsorption of ions and water, but to a lesser extent compared to the PCT.

3. **Determine the Type of Epithelium in PCT**:
- The PCT is lined with simple cuboidal epithelium that has a brush border. The brush border consists of microvilli that increase the surface area for absorption.

4. **Determine the Type of Epithelium in DCT**:
- The DCT is lined with simple cuboidal epithelium, but it does not have a brush border like the PCT.

5. **Summarize the Findings**:
- Therefore, the PCT has simple cuboidal epithelium with a brush border, while the DCT has simple cuboidal epithelium.

6. **Select the Correct Option**:
- Based on the analysis, the correct answer is that both the PCT and DCT are lined with simple cuboidal epithelium, with the PCT specifically having a brush border.

### Final Answer:
The type of tissue found in the PCT is simple cuboidal epithelium with a brush border, and the DCT is lined with simple cuboidal epithelium.
