3. General Characteristics
Next to free surface
Tightly packed
Simple (one layer) or stratified (many layers)

4. Types of Epithelial Tissue

Thin, flattened
Rapid diffusion
Kidneys

5. Types of Epithelial Tissue
Stratified squamos
Many layers allow quick replacement
Skin

6. Types of Epithelial Tissue
Transitional

When distended (stretched), looks like stratified squamous
Bladder

7. Types of Epithelial Tissue
Simple cuboidal
Secretion/
absorption
Glands, kidneys

8. Types of Epithelial Tissue
Glandular
Secretion
Cuboidal and goblet cells

9. WRAP UP Where do you find cuboidal epithelial tissue? What does it do?
Compare and contrast endocrine and exocrine glands.

10. WARM UP Give one general characteristic of all epithelial tissue.
Compare and contrast transitional and stratified squamos epithelium.

11. WRAP UP
Compare and contrast simple squamous and stratified squamous epithelial tissue.
