Skin is

Options

A. Cuboidal epithelium
B. Stratified epithelium
C. Columnar epithelium
D. Pseudostratified epithelium.

Answer

**Step-by-Step Text Solution:**

1. **Understanding the Question**: The question asks about the nature of skin and its classification based on the type of epithelium it comprises.

2. **Defining Skin**: Skin is the outer covering of the body and is recognized as the largest organ of the integumentary system. It serves multiple functions including protection, sensation, and regulation of body temperature.

3. **Identifying Types of Epithelium**: To answer the question, we need to identify the type of epithelial tissue that makes up the skin. The skin is primarily composed of stratified squamous epithelium.

4. **Differentiating Other Types of Epithelium**:
- **Simple Epithelium**: This type consists of a single layer of cells and is not found in the skin.
- **Stratified Epithelium**: This type consists of multiple layers of cells and is indeed present in the skin, providing durability and protection.
- **Columnar Epithelium**: Typically found in the digestive tract, not in the skin.
- **Pseudo-stratified Epithelium**: This type appears to be stratified but is actually a single layer of cells; it is found in the respiratory tract, not in the skin.

5. **Conclusion**: The skin is primarily made up of stratified squamous epithelium, which is essential for its protective functions.

**Final Answer**: The skin is made up of stratified squamous epithelium.
