Which of the following epithelium is commonly found in the ducts of glands and tubular parts of nephrons in kidneys and its main functions are secretion and absorption?

Options

A. Squamous epithelium
B. Cuboidal epithelium
C. Columnar epithelium
D. Ciliated epithelium

Answer

To solve the question about which type of epithelium is commonly found in the ducts of glands and the tubular parts of nephrons in kidneys, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Types of Epithelium**:
- We need to identify the different types of epithelial tissues mentioned: squamous, cuboidal, columnar, and ciliated epithelium.

2. **Analyze the Functions of Each Epithelium**:
- **Squamous Epithelium**: This type is thin and allows for diffusion and filtration. It is commonly found in areas like the lungs and blood vessels.
- **Cuboidal Epithelium**: This type is cube-shaped and is involved in secretion and absorption. It is typically found in the ducts of glands and the tubular parts of nephrons in the kidneys.
- **Columnar Epithelium**: This type is taller and often involved in absorption and secretion, but it is more commonly found in the digestive tract.
- **Ciliated Epithelium**: This type has hair-like structures (cilia) and is found in the respiratory tract and fallopian tubes, helping in the movement of mucus and other substances.

3. **Identify the Relevant Epithelium for the Question**:
- The question specifically asks for the epithelium found in the ducts of glands and the tubular parts of nephrons, with a focus on secretion and absorption.
- Based on the analysis, **cuboidal epithelium** fits this description perfectly as it is known for its role in secretion and absorption and is found in the specified locations.

4. **Select the Correct Answer**:
- Therefore, the correct answer to the question is **cuboidal epithelium**.

### Final Answer:
The epithelium commonly found in the ducts of glands and tubular parts of nephrons in kidneys, with the main functions of secretion and absorption, is **cuboidal epithelium**.
