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 is observed to have multiple layers of flat cells at the surface and cuboidal cells at the base. Which type of epithelium is this most likely to be?

Accepted Answer

Stratified squamous epithelium

Question 3

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

Accepted Answer

Has a high regenerative capacity

Question 4

A patient has a tumor that has penetrated the basement membrane and invaded underlying tissues. This is an example of:

Accepted Answer

Malignant cancerous invasion

Question 5

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

Accepted Answer

They receive nutrients by diffusion from underlying connective tissue

Question 6

Which type of gland releases its product by exocytosis without losing any part of the cell?

Accepted Answer

Merocrine gland

Question 7

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. This tissue is most likely:

Accepted Answer

Pseudostratified ciliated columnar epithelium

Question 8

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

Accepted Answer

Increase surface area for absorption

Question 9

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

Accepted Answer

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

Question 10

Which of the following is a correct pairing of gland type and its secretion method?

Accepted Answer

Merocrine gland – secretion by exocytosis

A tissue sample from the urinary bladder shows cells that change shape when stretched. This tissue is most likely:

Accepted Answer

Transitional epithelium

Question 12

Which of the following statements about the basement membrane is TRUE?

A gland that releases its product into the bloodstream rather than through a duct is classified as:

Accepted Answer

Endocrine

Question 15

Which of the following is a distinguishing feature of connective tissue that supports epithelial tissue?

Accepted Answer

It provides nutrients to the avascular epithelium

Question 16

Which of the following best explains why stratified squamous epithelium is found in areas subject to abrasion?

Accepted Answer

It provides a durable, protective barrier

Question 17

Which of the following is a correct description of the apical surface of epithelial tissue?

Accepted Answer

It faces the body surface or cavity

Question 18

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

Accepted Answer

Compound alveolar

Question 19

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

Accepted Answer

They prevent leakage of substances between adjacent cells

Question 20
