Question 1

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

Accepted Answer

Facilitation of rapid gas exchange due to thinness

Question 2

A tissue sample from the lining of the urinary bladder shows cells that change shape from rounded to flattened as the bladder fills. What type of epithelial tissue is this?

Accepted Answer

Transitional epithelium

Question 3

Which equation correctly represents the relationship between the number of cell layers ($n$) and the classification of epithelial tissue?

Accepted Answer

$n = 1$ \rightarrow$ Simple epithelium; \quad n > 1$ \rightarrow$ Stratified epithelium

Question 4

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

Accepted Answer

Lining of the mouth and esophagus

Question 5

A histology slide shows a single layer of cube-shaped cells with centrally located nuclei. Which function is most associated with this tissue type?

Accepted Answer

Absorption and secretion

Question 6

Which of the following statements about the nuclei in epithelial cells is correct?

Accepted Answer

Nuclei take on the same shape as the cell they are in

Question 7

Which type of epithelial tissue would you expect to find lining the inside of blood vessels, and what is its specific name?

Accepted Answer

Simple squamous epithelium, called endothelium

Question 8

Keratinized stratified squamous epithelium is best suited for which of the following functions?

Accepted Answer

Protection against dehydration and abrasion

Question 9

A patient has damage to the serous membrane lining the peritoneal cavity. Which type of epithelial tissue is primarily affected?

Accepted Answer

Simple squamous epithelium (mesothelium)

Question 10

Which of the following best explains why stratified epithelia are found in areas subject to mechanical or chemical stress?

Accepted Answer

Multiple layers provide increased protection against abrasion and injury

Question 11

Which of the following is a correct match between epithelial tissue type and its location?

Accepted Answer

Stratified squamous epithelium — lining of the esophagus

Question 12

Which of the following epithelial types is most likely to be found in large ducts of salivary glands?

Accepted Answer

Stratified columnar epithelium

Question 13

A tissue sample from the kidney tubules is examined under a microscope. Which epithelial type is most likely present?

Accepted Answer

Simple cuboidal epithelium

Question 14

Which of the following is a distinguishing feature of transitional epithelium compared to other epithelial types?

Accepted Answer

Cells can change shape from rounded to squamous-like depending on organ distension

Question 15

If a tissue is described as 'simple columnar epithelium,' which of the following best describes its structure?

Accepted Answer

Single layer of tall, rectangular cells

Question 16

Which of the following equations best represents the relationship between epithelial tissue function ($F$) and cell shape ($S$) for gas exchange?

Accepted Answer

$F = S_{squamous}$

Question 17

Which of the following is true regarding the basement membrane in epithelial tissues?

Accepted Answer

All epithelial cells are attached to the basement membrane

Question 18

A biopsy from the lining of the stomach reveals tall cells with nuclei near the base and some goblet cells. What is the most likely epithelial type?

Accepted Answer

Simple columnar epithelium

Question 19

Which of the following best describes the difference between mesothelium and endothelium?

Accepted Answer

Mesothelium lines serous membranes; endothelium lines blood vessels

Question 20

Which of the following is a correct application of epithelial tissue classification in a clinical scenario? A patient presents with chronic acid reflux damaging the lining of the esophagus. Which tissue type is most affected?

Accepted Answer

Stratified squamous epithelium
