column a
a. simple columnar epithelium
b. simple cuboidal epithelium
c. simple squamous epithelium
d. pseudostratified columnar epithelium
e. stratified squamous epithelium
f. stratified columnar epithelium
g. stratified cuboidal epithelium
h. transitional epithelium
column b

1. consists of several layers of varied - shaped cells, allowing an expandable lining
2. commonly possesses cilia that move dust and mucus out of the respiratory airways
3. single layer of flattened cells
4. single row of elongated cells with nuclei located at different levels, and some cells dont reach the free surface
5. forms walls of capillaries and air sacs of lungs
6. elongated cells with elongated nuclei located near the basement membrane
7. provides lining of urethra of males and parts of pharynx
8. provides abrasion protection of skin epidermis and oral cavity
9. forms inner lining of urinary bladder and ureters
10. lines kidney tubules and ducts of salivary glands
11. forms lining of stomach and intestines
12. two or three layers of cube - shaped cells
13. forms lining of oral cavity, anal canal, and vagina
14. possesses microvilli in small intestine to increase surface area for better absorption

Explanation:

1. Transitional epithelium has several - layered, variably - shaped cells for expandable lining, so it matches with the description of the inner lining of urinary bladder and ureters.
2. Pseudostratified columnar epithelium commonly has cilia to move dust and mucus in respiratory airways.
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 has a single row of elongated cells with nuclei at different levels and some cells not reaching the free surface.
5. Simple squamous epithelium forms walls of capillaries and air sacs of lungs.
6. Simple columnar epithelium has elongated cells with elongated nuclei near the basement membrane.
7. Stratified columnar epithelium provides lining of urethra of males and parts of pharynx.
8. Stratified squamous epithelium provides abrasion protection of skin epidermis and oral cavity.
9. Transitional epithelium forms inner lining of urinary bladder and ureters.
10. Simple cuboidal epithelium lines kidney tubules and ducts of salivary glands.
11. Simple columnar epithelium forms lining of stomach and intestines.
12. Stratified cuboidal epithelium has two or three layers of cube - shaped cells.
13. Stratified squamous epithelium forms lining of oral cavity, anal canal, and vagina.
14. Simple columnar epithelium possesses microvilli in small intestine to increase surface area for better absorption.
