Question 1

Which of the following best describes the function of simple squamous epithelium in the alveoli of the lungs?

Accepted Answer

Rapid diffusion of gases

Question 2

A tissue sample is being prepared for light microscopy. Which of the following steps is performed first?

Accepted Answer

Fixation with a solvent

Question 3

Which characteristic is unique to epithelial tissue compared to other basic tissue types?

Accepted Answer

Cells exhibit polarity with distinct apical and basal surfaces

Question 4

A patient presents with a tumor that has invaded underlying tissues beyond the basement membrane. What property of the basement membrane has been compromised?

Accepted Answer

Its role in resisting stretching and tearing

Question 5

Which of the following best explains why epithelial tissues are avascular but still able to receive nutrients?

Accepted Answer

They are nourished by diffusion from underlying connective tissue

Question 6

Which type of epithelial tissue is most likely to be found lining the urinary bladder, and what is its main functional advantage?

Accepted Answer

Transitional; allows stretching and increased storage

Question 7

A gland that releases its product by exocytosis without damaging the secretory cell is classified as which type?

Accepted Answer

Merocrine

Question 8

Which of the following is a correct pairing of epithelial tissue type and its primary location?

Accepted Answer

Stratified squamous – epidermis of the skin

Question 9

Which of the following best describes the difference between endocrine and exocrine glands?

Accepted Answer

Endocrine glands secrete hormones into interstitial fluid; exocrine glands secrete products onto body surfaces or into cavities

Question 10

A multicellular exocrine gland with a branched duct and sac-like secretory units is classified as which type?

Accepted Answer

Compound alveolar

Question 11

Which of the following cell junctions is primarily responsible for preventing molecules from passing between adjacent epithelial cells?

Accepted Answer

Tight junctions

Question 12

A biopsy from the lining of the trachea reveals cells of varying heights, all attached to the basement membrane, with cilia on the apical surface. Which type of epithelium is this?

Accepted Answer

Pseudostratified columnar

Question 13

Which of the following best explains why epithelial tissues have a high regenerative capacity?

Accepted Answer

They are exposed to friction and hostile environments, requiring frequent replacement

Question 14

Which of the following is a function of goblet cells found in the respiratory and digestive tracts?

Accepted Answer

Production of mucin for mucus formation

Question 15

A sweat gland that accumulates its product until the cell ruptures and is replaced by division of underlying cells is classified as:

Accepted Answer

Holocrine

Question 16

Which of the following best describes the structure of the basement membrane?

Accepted Answer

A combination of basal lamina and reticular lamina

Question 17

A pathologist is examining a tissue sample and notes the presence of microvilli on the apical surface. What is the most likely function of this tissue?

Accepted Answer

Absorption

Question 18

Which of the following statements about stratified epithelia is correct?

Accepted Answer

They are found in areas subject to wear and tear

Question 19

A glandular structure is composed of both tubular and alveolar secretory units and has a branched duct. How is this gland classified?

Accepted Answer

Compound tubuloalveolar

Question 20

Which of the following best describes the process by which endocrine glands release their products?

Accepted Answer

By exocytosis into interstitial fluid, then into blood or lymph
