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 critical for the skin's ability to heal after such an injury?

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 of gland?

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 multiple layers of flat cells at the surface and cuboidal cells at the base. Which type of epithelium is this?

Accepted Answer

Stratified squamous epithelium

Question 7

Which of the following statements about exocrine glands is correct?

Accepted Answer

They release their products onto body surfaces or into body cavities

Question 8

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

Accepted Answer

Disruption of directional transport across the tissue

Question 9

Which connective tissue type is primarily responsible for storing energy in the form of fat?

Accepted Answer

Adipose connective tissue

Question 10

A patient presents with a tumor that originated in the epithelial lining of the colon. Which of the following best explains why most cancers arise from epithelial tissues?

Accepted Answer

Epithelial tissues have a high rate of cell division, increasing the chance of mutations

Question 11

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

Accepted Answer

Exocrine glands secrete products onto surfaces or into cavities; endocrine glands secrete hormones directly into the blood

Question 12

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

Accepted Answer

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

Question 13

A tissue sample is found to have a large amount of extracellular matrix with collagen fibers and few cells. Which type of tissue is this most likely to be?

Accepted Answer

Connective tissue

Question 14

Which of the following best explains why simple columnar epithelium is found lining the stomach and intestines?

Accepted Answer

It is specialized for absorption and secretion

Question 15

A glandular cell ruptures to release its secretions, destroying itself in the process. This is an example of which mode of secretion?

Accepted Answer

Holocrine

Question 16

Which connective tissue type is most likely to be found in tendons and ligaments, and why?

Accepted Answer

Dense regular connective tissue; because it has parallel collagen fibers providing tensile strength

Question 17

A patient with a genetic defect in the formation of specialized contacts between epithelial cells would most likely experience which of the following?

Accepted Answer

Increased risk of dehydration due to loss of barrier function

Question 18

Which of the following is a function of areolar connective tissue?

Accepted Answer

Wraps and cushions organs

Question 19

A tissue sample from the urinary bladder shows cells that can change shape and appear both squamous and cuboidal. What type of epithelium is this?

Accepted Answer

Transitional epithelium

Question 20

Which of the following best describes the role of the basal surface of epithelial tissue?

Accepted Answer

It is next to underlying connective tissue and anchors the epithelium
