Question

part a assessments
match the tissues in column a with the characteristics in column b. place the letter of your choice in the space provided. (some answers may be used more than once.)
column a
a. simple columnar epithelium
b. simple cuboidal epithelium
c. simple squamous epithelium
d. pseudostratified columnar epithelium
e. stratified squamous epithelium
f. transitional epithelium
column b

1. consists of several layers of cells, allowing an expandable lining

d 2. commonly possesses cilia that move dust and mucus out of the respiratory airways

1. single layer of flattened cells
2. nuclei located at different levels within a single row of aligned cells

c 5. forms walls of capillaries and air sacs of lungs

1. appears layered (stratified) but is a single layer of cells (simple)
2. deeper cells cuboidal, or columnar; older cells flattened nearest the free surface

f 8. forms inner lining of urinary bladder
b 9. lines kidney tubules and ducts of salivary glands

1. forms lining of stomach and intestines
2. elongated cells with elongated nuclei located near basement membrane

e 12. forms lining of oral cavity, esophagus, anal canal, and vagina

Explanation:

To solve this tissue - characteristic matching problem, we analyze each tissue type and its corresponding characteristics:

1. Characteristic 1: Consists of several layers of cells, allowing an expandable lining

Transitional epithelium (f) has multiple cell layers and can stretch, so the answer is f.

2. Characteristic 2: Commonly possesses cilia that move dust and mucus out of the respiratory airways

Pseudostratified columnar epithelium (d) often has cilia for this function, so the answer is d.

3. Characteristic 3: Single layer of flattened cells

Simple squamous epithelium (c) is a single layer of flat cells, so the answer is c.

4. Characteristic 4: Nuclei located at different levels within a single row of aligned cells

Pseudostratified columnar epithelium (d) has nuclei at different levels in a single row of cells, so the answer is d.

5. Characteristic 5: Forms walls of capillaries and air sacs of lungs

Simple squamous epithelium (c) is found in these locations, so the answer is c.

6. Characteristic 6: Appears layered (stratified) but is a single layer of cells (simple)

Pseudostratified columnar epithelium (d) has this appearance, so the answer is d.

7. Characteristic 7: Deeper cells cuboidal, or columnar; older cells flattened nearest the free surface

Stratified squamous epithelium (e) has this cell - shape change with depth, so the answer is e.

8. Characteristic 8: Forms inner lining of urinary bladder

Transitional epithelium (f) lines the urinary bladder, so the answer is f.

9. Characteristic 9: Lines kidney tubules and ducts of salivary glands

Simple cuboidal epithelium (b) is found in these tubules and ducts, so the answer is b.

10. Characteristic 10: Forms lining of stomach and intestines

Simple columnar epithelium (a) lines the stomach and intestines, so the answer is a.

11. Characteristic 11: Elongated cells with elongated nuclei located near basement membrane

Simple columnar epithelium (a) has elongated cells with nuclei near the basement membrane, so the answer is a.

12. Characteristic 12: Forms lining of oral cavity, esophagus, anal canal, and vagina

Stratified squamous epithelium (e) lines these areas, so the answer is e.
