Question 1

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

Accepted Answer

Rapid diffusion of gases

Question 2

A tissue sample from the lining of the urinary bladder shows cells that appear cuboidal when relaxed and squamous when stretched. What type of epithelium is this?

Accepted Answer

Transitional epithelium

Question 3

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

Accepted Answer

Is avascular but innervated

Question 4

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

Accepted Answer

Merocrine

Question 5

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

Accepted Answer

They are exposed to friction and hostile environments, stimulating cell division

Question 6

Which of the following is a function of the noncellular basal lamina found in epithelial tissues?

Accepted Answer

Acts as a selective filter and scaffolding for cell migration

Question 7

A patient has a genetic defect affecting the formation of tight junctions in epithelial tissue. Which of the following is a likely consequence?

Accepted Answer

Increased permeability between cells

Question 8

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

Accepted Answer

Endocrine glands are ductless and secrete hormones into blood or lymph; exocrine glands secrete products into ducts

Question 9

Which of the following epithelial types is best suited for absorption and secretion in the kidney tubules?

Accepted Answer

Simple cuboidal epithelium

Question 10

A biopsy from the trachea reveals a single layer of cells of varying heights, with nuclei at different levels and cilia on the apical surface. What is the most likely tissue type?

Accepted Answer

Pseudostratified ciliated columnar epithelium

Question 11

Which of the following statements about stratified squamous epithelium is correct?

Accepted Answer

It is found in areas subject to abrasion, such as the mouth and esophagus

Question 12

Which of the following best describes the function of goblet cells in the respiratory and digestive tracts?

Accepted Answer

Production of mucin that forms mucus for protection and lubrication

Question 13

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

Accepted Answer

Compound alveolar

Question 14

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

Accepted Answer

Simple columnar epithelium – absorption in the digestive tract

Question 15

Which of the following equations best represents the relationship between the rate of diffusion ($$R$$), surface area ($$A$$), and membrane thickness ($$d) in $$simple squamous epithelium?

Accepted Answer

$$R = \frac{A}{d}$$

Question 16

A patient with a burn injury loses the protective function of their skin. Which epithelial tissue is primarily affected?

Accepted Answer

Stratified squamous keratinized epithelium

Question 17

Which of the following best explains why epithelial tissues are supported by connective tissue?

Accepted Answer

To provide nutrients and structural support due to their avascular nature

Question 18

Which of the following is a correct description of the basement membrane in epithelial tissues?

Accepted Answer

It consists of the basal lamina and reticular lamina, reinforcing the epithelial sheet

Question 19

Which of the following best describes the secretion mechanism of holocrine glands?

Accepted Answer

Entire secretory cells rupture, releasing secretions and cell fragments

Question 20

A researcher is studying a tissue with the following features: cells with polarity, specialized contacts, supported by connective tissue, avascular but innervated, and high regenerative capacity. Which tissue type is being described?

Accepted Answer

Epithelial tissue
