3. Simple columnar Locations:
Nonciliated lines the inside of the digestive tract.
Ciliated lines small bronchi and uterine tubes.

4. Simple columnar Functions: Absorption Secretes mucus and enzymes
Ciliated: Propels mucus/egg cells

7. Transitional Locations:
Lines urinary bladder and urinary tubes (ureter & urethra).
Function:
Able to stretch to accommodate urine.

10. Simple cuboidal Locations: Kidney tubules
Ducts and secretory parts of small glands
Ovary surface

11. Simple cuboidal
Functions:
Secretion & absorption

14. Simple squamous Locations: Kidney glomerulus
Air sacs (alveoli) of lungs
Lines heart, blood vessels and lymphatic vessels
Ventral body cavity lining (serosa)

15. Simple squamous
Functions:
Diffusion
Filtration
Secretes serous fluid

18. Stratified squamous Location: Epidermis of the skin (dry, keratinized)
Moist linings of mouth and esophagus (nonkeratinized)
Function:
Protects underlying layers from abrasion.

21. Pseudostratified Locations:
Sperm tubes and ducts of large glands (nonciliated)
Trachea and upper respiratory tract.
Function:
Secretion of mucus and movement of mucus if ciliated.
