The epithelium present in the lining of stomach and intestine is:

Options

A. simple squamous
B. simple cuboidal
C. simple columnar
D. stratified squamous

Answer

To determine the type of epithelium present in the lining of the stomach and intestine, we can analyze the options provided step by step:

### Step 1: Analyze the Options
We have four options to consider:
1. Simple Squamous
2. Simple Cuboidal
3. Simple Columnar
4. Stratified Squamous

### Step 2: Evaluate Simple Squamous Epithelium
- **Description**: Simple squamous epithelium consists of a single layer of flat cells.
- **Function**: It is permeable and allows for easy diffusion and filtration.
- **Location**: Found in areas like the walls of capillaries and alveoli of lungs.
- **Conclusion**: This type of epithelium is not found in the lining of the stomach and intestine.

### Step 3: Evaluate Simple Cuboidal Epithelium
- **Description**: Simple cuboidal epithelium consists of a single layer of cube-shaped cells.
- **Function**: Primarily involved in secretion and absorption.
- **Location**: Found in kidney tubules, pancreas, and salivary glands.
- **Conclusion**: This type of epithelium is also not present in the lining of the stomach and intestine.

### Step 4: Evaluate Simple Columnar Epithelium
- **Description**: Simple columnar epithelium consists of a single layer of column-shaped cells with oval nuclei located at the base.
- **Function**: It is involved in secretion and absorption.
- **Location**: This epithelium lines most organs of the digestive tract, including the stomach and intestines.
- **Conclusion**: This is the correct type of epithelium present in the lining of the stomach and intestine.

### Step 5: Evaluate Stratified Squamous Epithelium
- **Description**: Stratified squamous epithelium consists of multiple layers of flattened cells.
- **Function**: Provides protection against abrasion and desiccation.
- **Location**: Found in the outer layer of skin, mouth, esophagus, and vagina.
- **Conclusion**: This type of epithelium is not found in the lining of the stomach and intestine.

### Final Answer
The epithelium present in the lining of the stomach and intestine is **Simple Columnar Epithelium**.
