Which of the following groups consists of
organs having innermost lining of Columnar
epithelium ?

Options

A. Stomach, Fallopian tube, lung ,alveoli
B. Gall bladder, stomach artery
C. Intestine, gastric gland , gall bladder
D. Gastric gland, poncreatic duct , veins

Answer

To determine which group consists of organs having an innermost lining of columnar epithelium, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Columnar Epithelium**:
- Columnar epithelium is characterized by a single layer of tall, column-shaped cells. These cells are attached to a basement membrane and typically have oval-shaped nuclei.

2. **Identify Locations of Columnar Epithelium**:
- This type of epithelium is commonly found in organs associated with the digestive system, such as:
- The intestines
- Gastric glands
- Gallbladder

3. **Analyze the Options Provided**:
- Review the options given in the question to identify which group includes the organs lined with columnar epithelium.
- For example:
- **Option A**: Fallopian tubes (lined with ciliated columnar epithelium)
- **Option B**: Kidneys (lined with squamous epithelium)
- **Option C**: Pancreatic ducts (lined with cuboidal epithelium)
- **Option D**: Intestine, gastric gland, and gallbladder (lined with columnar epithelium)

4. **Select the Correct Option**:
- Based on the analysis, the correct option is **Option D**: Intestine, gastric gland, and gallbladder, as these organs have an innermost lining of columnar epithelium.

### Final Answer:
The group that consists of organs having an innermost lining of columnar epithelium is **Option D: Intestine, gastric gland, and gallbladder**.
