Question 1

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

Accepted Answer

Facilitating rapid diffusion of gases

Question 2

A tissue sample from the kidney tubules shows a single layer of cube-shaped cells. What is the most likely tissue type?

Accepted Answer

Simple cuboidal epithelium

Question 3

Which structural feature of epithelial cells increases their surface area for absorption, especially in the small intestine?

Accepted Answer

Microvilli

Question 4

A researcher observes a tissue with multiple layers of flat, scale-like cells. Which function is most likely associated with this tissue?

Accepted Answer

Protection against abrasion

Question 5

Which equation best represents the relationship between surface area ($$A) $$and the number of microvilli ($$n) on an $$epithelial cell, if each microvillus adds an area $$a$$?

Accepted Answer

$$A = n 	imes a$$

Question 6

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

Accepted Answer

It contains large amounts of collagen fibers in the matrix

Question 7

A patient has damage to the basement membrane of their epithelial tissue. Which consequence is most likely?

Accepted Answer

Impaired attachment of epithelial cells to connective tissue

Question 8

Which tissue type is most likely to be found lining the urinary bladder, allowing it to stretch as it fills?

Accepted Answer

Transitional epithelium

Question 9

If a tissue sample contains cells of varying heights, all touching the basement membrane but appearing stratified, which type of epithelium is this?

Accepted Answer

Pseudostratified columnar epithelium

Question 10

Which of the following best explains why simple cuboidal epithelium is well-suited for secretion and absorption in kidney tubules?

Accepted Answer

Its cube-shaped cells have a large volume for organelles involved in transport

Question 11

A tissue sample from the trachea shows tall cells with cilia and goblet cells, appearing to have multiple layers but all cells touch the basement membrane. What is the main function of this tissue?

Accepted Answer

Secretion and movement of mucus

Question 12

Which of the following is the correct sequence for classifying epithelial tissue?

Accepted Answer

Number of layers, shape of cell

Question 13

Which of the following equations would you use to calculate the total number of cells ($$N) in a $$simple cuboidal epithelium covering an area $$A$$, if each cell has a surface area $$a$$?

Accepted Answer

$$N = A / a$$

Question 14

Which of the following is a key difference between simple and stratified epithelial tissues?

Accepted Answer

Simple epithelia consist of a single layer of cells, stratified have multiple layers

Question 15

Which of the following best describes the role of the basement membrane in epithelial tissue?

Accepted Answer

It anchors epithelial cells to underlying connective tissue

Question 16

A biopsy from the esophagus reveals multiple layers of cells with the most superficial cells being flat. What is the most likely tissue type?

Accepted Answer

Stratified squamous epithelium

Question 17

Which of the following is a real-world consequence of damage to simple squamous epithelium in the alveoli?

Accepted Answer

Impaired gas exchange leading to decreased oxygenation of blood

Question 18

Which of the following epithelial tissue types is most likely to be found in areas subject to friction, such as the skin or mouth?

Accepted Answer

Stratified squamous epithelium

Question 19

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

Accepted Answer

Simple cuboidal epithelium – kidney tubules

Question 20

Which of the following best explains why stratified squamous epithelium is found in the epidermis of the skin?

Accepted Answer

It provides a thick, protective barrier against mechanical injury and pathogens
