Question 1

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

Accepted Answer

Contains abundant extracellular matrix

Question 2

A patient suffers a severe burn that destroys the epidermis. Which property of epithelial tissue is most important for recovery?

Accepted Answer

Regeneration

Question 3

Which type of epithelial tissue is best suited for rapid diffusion and filtration, and where is it commonly found?

Accepted Answer

Simple squamous epithelium; air sacs of lungs

Question 4

A gland that releases its secretion by exocytosis without damaging the cell is classified as which type?

Accepted Answer

Merocrine

Question 5

Which of the following best describes the function of connective tissue?

Accepted Answer

Supports, protects, and binds other tissues

Question 6

A biopsy reveals a tissue with a single layer of tall, closely packed cells with oval nuclei. Which type of epithelium is this?

Accepted Answer

Simple columnar epithelium

Question 7

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

Accepted Answer

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

Question 8

Which connective tissue type is the prototype (model) for all other connective tissues and is found widely distributed under epithelia?

Accepted Answer

Areolar connective tissue

Question 9

A mutation causes epithelial cells to lose their polarity. Which of the following consequences is most likely?

Accepted Answer

Cells will no longer have distinct apical and basal surfaces

Question 10

Which of the following best explains why epithelial tissues are avascular but still able to receive nutrients?

Accepted Answer

They receive nutrients by diffusion from underlying connective tissue

Question 11

A multicellular exocrine gland with branched ducts and secretory cells arranged in sacs is classified as:

Accepted Answer

Compound alveolar

Question 12

Which of the following tissues would you expect to find lining the urinary bladder, allowing it to stretch as it fills?

Accepted Answer

Transitional epithelium

Question 13

80% of cancers arise from which type of tissue, and why is this tissue particularly susceptible?

Accepted Answer

Epithelial tissue; because it regenerates rapidly and is exposed to environmental insults

Question 14

Which of the following best describes the function of goblet cells?

Accepted Answer

Produce mucus to lubricate and protect surfaces

Question 15

A tissue sample shows multiple layers of flat cells at the surface and cuboidal cells at the base. What is the most likely function of this tissue?

Accepted Answer

Protection from abrasion

Question 16

Which connective tissue type is specialized for energy storage and insulation?

Accepted Answer

Adipose tissue

Question 17

A patient with a genetic defect in collagen synthesis would most likely have problems with which tissue type?

Accepted Answer

Connective tissue

Question 18

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

Accepted Answer

Elastic cartilage; provides flexible support

Question 19

A gland that accumulates its product until the cell ruptures, releasing both secretion and cell fragments, is classified as:

Accepted Answer

Holocrine

Question 20

Which of the following best explains why simple squamous epithelium is found in the alveoli of the lungs?

Accepted Answer

It allows for rapid gas exchange due to its thinness
