Question 1

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

Accepted Answer

Passage of materials by passive diffusion and filtration

Question 2

A biopsy from a patient's trachea reveals an epithelial tissue with cells of varying heights, all attached to the basement membrane, some bearing cilia and goblet cells. Which type of epithelium is this?

Accepted Answer

Pseudostratified columnar epithelium

Question 3

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

Accepted Answer

Abundant extracellular matrix

Question 4

A patient suffers a burn that destroys the epidermis. Which type of epithelial tissue is primarily affected?

Accepted Answer

Stratified squamous keratinized epithelium

Question 5

Which of the following best explains why epithelial tissues are able to regenerate quickly after injury?

Accepted Answer

They are supported by connective tissue and have high rates of cell division

Question 6

Which tissue type is responsible for covering body surfaces and lining body cavities?

Accepted Answer

Epithelial tissue

Question 7

A gland is composed of a single layer of cubelike cells with large, spherical central nuclei. Which function is most likely associated with this tissue?

Accepted Answer

Secretion and absorption

Question 8

Which of the following locations is most likely to contain nonkeratinized stratified squamous epithelium?

Accepted Answer

Lining of the esophagus

Question 9

A tissue sample from the uterine tube shows a single layer of tall, ciliated cells. What is the primary function of this epithelium?

Accepted Answer

Propulsion of reproductive cells by ciliary action

Question 10

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

Accepted Answer

Simple epithelia have a single layer of cells attached to the basement membrane; stratified epithelia have multiple layers with only the basal layer attached to the basement membrane

Question 11

A histological slide shows ducts of a large sweat gland lined by two layers of cube-shaped cells. Which type of epithelium is present?

Accepted Answer

Stratified cuboidal epithelium

Question 12

Which of the following is a function of epithelial tissue that is especially important in the kidney glomeruli?

Accepted Answer

Filtration of blood

Question 13

A patient with chronic acid reflux is at risk for damage to which type of epithelial tissue lining the esophagus?

Accepted Answer

Nonkeratinized stratified squamous epithelium

Question 14

Which of the following best explains why epithelial tissues are avascular?

Accepted Answer

They receive nutrients by diffusion from underlying connective tissue

Question 15

Which of the following is a rare epithelial tissue found in the male urethra and large ducts of some glands?

Accepted Answer

Stratified columnar epithelium

Question 16

A tissue sample from the lining of the small intestine is examined. Which of the following features would you expect to find?

Accepted Answer

Single layer of columnar cells, some with microvilli and goblet cells

Question 17

Which of the following equations best represents the relationship between the rate of diffusion ($D$), surface area ($A$), and thickness ($T$) of a simple squamous epithelium, as seen in the alveoli?

Accepted Answer

$D = \frac{A}{T}$

Question 18

Which of the following is a real-world consequence of the loss of polarity in epithelial cells?

Accepted Answer

Disruption of directional secretion and absorption, leading to diseases such as cancer

Question 19

A patient presents with a genetic disorder that prevents the formation of tight junctions between epithelial cells. Which of the following is a likely consequence?

Accepted Answer

Uncontrolled passage of substances between cells

Question 20

Which of the following best describes the function of goblet cells found in some epithelial tissues?

Accepted Answer

Secretion of mucus
