2. commonly possesses cilia that move dust and mucus out of the respiratory airways
3. single layer of flattened cells
4. nuclei located at different levels within a single row of aligned cells
5. forms walls of capillaries and air sacs of lungs
6. appear layered (stratified) but are a single layer of cells (simple)
7. deeper cells cuboidal, or columnar, older cells flattened nearest the free surface
8. forms inner lining of urinary bladder
9. lines kidney tubules and ducts of salivary glands
10. forms lining of stomach and intestines
11. elongated cells with elongated nuclei located near basement membrane
12. forms lining of oral cavity, esophagus, anal canal, and vagina

Explanation:

1. Simple columnar epithelium has elongated cells with elongated nuclei near basement membrane and forms lining of stomach and intestines.
2. Simple cuboidal epithelium lines kidney tubules and ducts of salivary glands.
3. Simple squamous epithelium is a single - layer of flattened cells and forms walls of capillaries and air sacs of lungs.
4. Pseudostratified columnar epithelium commonly possesses cilia that move dust and mucus out of the respiratory airways and appears layered but is a single layer of cells.
5. Stratified squamous epithelium consists of several layers of cells, and forms lining of oral cavity, esophagus, anal canal, and vagina.
6. Transitional epithelium consists of several layers of cells allowing an expandable lining and forms inner lining of urinary bladder.
