______epithelium consists of two or more cell layers and has protective function as it does to our skin.

Answer

To answer the question regarding the type of epithelium that consists of two or more cell layers and has a protective function, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Epithelium**: Epithelium is a type of tissue that covers the body surfaces, lines cavities and organs, and forms glands. It serves various functions including protection, absorption, secretion, and sensation.

2. **Identifying Layers**: The question specifies that the epithelium consists of two or more cell layers. This indicates that we are looking for a type of epithelium that is stratified, as opposed to simple epithelium which has only one layer.

3. **Protective Function**: The question also mentions that this epithelium has a protective function similar to that of the skin. This suggests that the epithelium in question is involved in protecting underlying tissues from physical damage, pathogens, and dehydration.

4. **Types of Stratified Epithelium**: The most common type of stratified epithelium that provides protection is stratified squamous epithelium. This type consists of multiple layers of cells, with the outermost layer being flat (squamous) in shape.

5. **Characteristics of Stratified Squamous Epithelium**: Stratified squamous epithelium is characterized by:
- Multiple layers of cells.
- The outermost cells are flattened (squamous).
- It is found in areas subject to abrasion, such as the skin, mouth, and esophagus.

6. **Conclusion**: Based on the above analysis, the answer to the question is that the type of epithelium consisting of two or more cell layers and having a protective function is **stratified squamous epithelium**.

### Final Answer:
**Stratified squamous epithelium**
