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 patient suffers a severe burn that destroys the epidermis and underlying connective tissue. Which membrane and tissue types are primarily affected?

Accepted Answer

Cutaneous membrane and epithelial/connective tissue

Question 3

Which of the following statements about connective tissue is TRUE?

Accepted Answer

All connective tissues arise from mesenchyme

Question 4

A biopsy reveals tissue with closely packed cells, an apical surface, and no blood vessels. Which tissue type is this most likely to be?

Accepted Answer

Epithelial tissue

Question 5

Which of the following best explains why cartilage injuries heal slowly in adults?

Accepted Answer

Cartilage is avascular and relies on diffusion for nutrient supply

Question 6

Which type of gland releases its product by exocytosis without losing cellular material, and what is an example?

Accepted Answer

Merocrine; sweat gland

Question 7

A tissue sample shows parallel bundles of collagen fibers with few cells and poor vascularization. Which tissue is this and what is its primary function?

Accepted Answer

Dense regular connective tissue; resists tension in one direction

Question 8

Which of the following is a key difference between endocrine and exocrine glands?

Accepted Answer

Endocrine glands secrete hormones into interstitial fluid; exocrine glands secrete onto body surfaces or into cavities

Question 9

Which connective tissue fiber type is most responsible for providing high tensile strength to tissues such as tendons?

Accepted Answer

Collagen fibers

Question 10

A patient with a heart attack develops scar tissue in the myocardium. Which process is primarily responsible for this, and what is a possible consequence?

Accepted Answer

Fibrosis; impaired contractile function

Question 11

Which of the following tissues has the highest regenerative capacity?

Accepted Answer

Epithelial tissue

Question 12

Which of the following best describes the structure and function of transitional epithelium?

Accepted Answer

Multiple layers of cells that change shape; allows stretching of urinary organs

Question 13

Which cell type is responsible for producing the extracellular matrix in bone tissue?

Accepted Answer

Osteoblast

Question 14

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

Accepted Answer

Universal packing material between other tissues

Question 15

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

Accepted Answer

They receive nutrients by diffusion from underlying connective tissue and are supplied by nerve fibers

Question 16

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

Accepted Answer

Hyaline cartilage – costal cartilage of ribs

Question 17

Which of the following best describes the role of mast cells in connective tissue?

Accepted Answer

Initiate local inflammatory response

Question 18

A tissue sample from the trachea shows ciliated cells and mucus-secreting goblet cells. Which epithelial type is this?

Accepted Answer

Pseudostratified columnar epithelium

Question 19

Which of the following best describes the difference between regeneration and fibrosis during tissue repair?

Accepted Answer

Regeneration restores original tissue function; fibrosis replaces tissue with connective tissue

Question 20

Which of the following is a characteristic of cardiac muscle tissue?

Accepted Answer

Branched, striated cells with intercalated discs
