4. Stratified squamous epithelium - protective layers help in preventing water and other substances.

5. Pseudostratified columnar epithelium - secretes mucus to trap particles and cilia sweep entrapped particles up and out of the body,

6. Stratified columnar epithelium - protective lining of larger ducts,

7. Stratified cuboidal epithelium - protective lining of ducts,

8. Glandular epithelium - produce and release substances body fluids and ducts.

9. Transitional epithelium - makes the inner lining of the ureters and urinary bladders.
