Read each question carefully and answer to the best of your knowledge. Refer to your notes and textbook if needed.
1. Which of the following is NOT a primary function of epithelial tissue?
Protection
Secretion
Contraction
Absorption
2. Simple squamous epithelium is best suited for:
Areas requiring high protection against abrasion
Rapid diffusion and filtration
Secretion and absorption in glands
Movement of mucus along surfaces
3. Epithelial tissues are characterized by closely packed cells with little to no space.
4. The membrane anchors epithelial tissue to underlying connective tissue.
5. epithelium appears to have multiple layers but actually consists of a single layer of cells of varying heights.
6. All epithelial tissues are avascular, meaning they lack blood vessels.
True
False
7. Transitional epithelium is found lining the urinary bladder, allowing for stretching.
True
False
8. Describe the key structural differences between simple and stratified epithelial tissues.
9. Explain how the structure of columnar epithelium in the digestive tract relates to its function.
10. Observe the image below of transitional epithelium. Where in the body would you typically find this type of tissue, and what is its primary role?
