I. Epithelial Tissue
Four main kinds of Tissue
1. Epithelial Tissue
2. Connective Tissue
3. Muscle Tissue
4. Nervous Tissue

Epithelial Tissue classified by arrangement of cells:
• Simple (Simple squamous epithelium)
- Single layer of scalelike cells
Function: transportation

• Stratified (Stratified squamous epithelium)
- Several layers of closely packed cells, multiple layers of thin irregularly
shaped cells.
Function: Protection (primary)

Epithelial Tissue can be classified as:
- Covers the body and lines the cavities
- Classified based on the number of cells and the number of the layers
- Forms a continues sheet of cells with no blood vessels.

Cell shaped of Epithelial tissue:
• Squamous
• Cuboidal
• Columnar
• Transitional

Examples of Epithelial tissue:
• Simple columnar epithelium
- Columnar cells arranged in a single layer
- Line stomach and intestines
- Contain mucus-producing goblet cells
- Specialized for absorption
Example: Digestive system

• Stratified squamous epithelium
- Found in the areas, such as urinary bladder, that stretch
