Rapid diffusion of gases

Question 2

A patient presents with a tumor that has invaded underlying tissues from the epithelial layer. Which structure did the cancerous cells most likely breach?

Accepted Answer

Basement membrane

Question 3

Which of the following is NOT a characteristic of epithelial tissue?

Accepted Answer

Contains abundant blood vessels

Question 4

A gland that releases its product by exocytosis without losing cellular material is classified as which type?

Accepted Answer

Merocrine

Question 5

Which type of epithelial tissue is best suited for areas subject to wear and tear, such as the skin?

Accepted Answer

Stratified squamous

Question 6

Which of the following best explains why epithelial tissues heal quickly after injury?

Accepted Answer

They have a high rate of cell division

Question 7

A tissue sample from the trachea shows cells of varying heights, nuclei at different levels, and cilia on the apical surface. What is the most likely tissue type?

Accepted Answer

Pseudostratified ciliated columnar epithelium

Question 8

Which of the following statements about glandular epithelia is TRUE?

Accepted Answer

Exocrine glands release their products onto body surfaces or into body cavities

Question 9

A biopsy from the urinary bladder reveals an epithelium with cells that change shape when stretched. What is this tissue called?

Accepted Answer

Transitional epithelium

Question 10

Which of the following best describes the difference between simple and stratified epithelia?

Accepted Answer

Simple epithelia are specialized for absorption and filtration; stratified epithelia are specialized for protection

Question 11

Which of the following is a function of microvilli on the apical surface of epithelial cells?

Accepted Answer

Increase surface area for absorption

Question 12

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

Accepted Answer

Compound alveolar

Question 13

Which of the following best describes the role of tight junctions in epithelial tissue?

Accepted Answer

Prevent substances from passing between adjacent cells

Question 14

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

Accepted Answer

Simple columnar epithelium – lining of the digestive tract

Question 15

Which of the following best explains why epithelial tissue is avascular?

Accepted Answer

It relies on diffusion from underlying connective tissue for nutrients

Question 16

A gland that accumulates its product until the cell ruptures, releasing both the secretion and cell fragments, is classified as:

Accepted Answer

Holocrine

Question 17

Which of the following is a distinguishing feature of pseudostratified columnar epithelium?

Accepted Answer

Nuclei are at different levels, giving a false impression of stratification

Question 18

Which of the following best describes the function of goblet cells?

Accepted Answer

Secretion of mucus

Question 19

Which of the following is TRUE regarding the basement membrane?

Accepted Answer

It reinforces the epithelial sheet and resists stretching and tearing

Question 20

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

Accepted Answer

Endocrine glands secrete hormones into the blood; exocrine glands secrete products onto surfaces or into cavities
