Question 1

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

Accepted Answer

They form a barrier that prevents substances from passing between cells.

Question 2

A tissue sample from the lining of the urinary bladder is examined under a microscope. The cells appear to be able to stretch and relax, and the tissue prevents diffusion of urine back into the body. Which type of epithelial tissue is this?

Accepted Answer

Transitional epithelium

Question 3

Which of the following is a characteristic unique to epithelial tissue compared to other tissue types?

Accepted Answer

Has a high rate of cell division and renewal

Question 4

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

Accepted Answer

Merocrine gland

Question 5

A patient has damage to the desmosomes in their epithelial cells. Which of the following symptoms would most likely result?

Accepted Answer

Reduced ability of cells to adhere to each other under mechanical stress

Question 6

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

Accepted Answer

Establishes structural framework and supports other tissues

Question 7

Which equation correctly represents the relationship between the number of layers ($$n) in $$stratified epithelium and the rate of cell loss ($$R) $$from the surface, assuming cell loss increases with more layers?

Accepted Answer

$$R = k 	imes n$$

Question 8

Which type of epithelial tissue is best suited for rapid diffusion of gases in the lungs?

Accepted Answer

Simple squamous epithelium

Question 9

A gland that secretes hormones into the bloodstream is classified as which type of gland?

Accepted Answer

Endocrine gland

Question 10

Which of the following is NOT a function of connective tissue?

Accepted Answer

Secretion of digestive enzymes

Question 11

Which type of epithelial tissue lines the trachea and is often ciliated to help move mucus?

Accepted Answer

Pseudostratified columnar epithelium

Question 12

Which of the following best explains why epithelial tissue is avascular?

Accepted Answer

It relies on diffusion from underlying connective tissue for nutrients.

Question 13

Which type of connective tissue is most abundant and provides an open framework for organs?

Accepted Answer

Loose connective tissue

Question 14

A tissue sample from the skin shows many layers of cells, with the outermost cells flattened. What type of epithelial tissue is this?

Accepted Answer

Stratified squamous epithelium

Question 15

Which of the following is a function of the basement membrane in epithelial tissue?

Accepted Answer

It connects epithelium to underlying connective tissue.

Question 16

Which type of secretion involves the entire cell becoming packed with secretory products and then bursting?

Accepted Answer

Holocrine secretion

Question 17

Which of the following best describes the structure of simple columnar epithelium?

Accepted Answer

Single layer of tall cells, often with microvilli for absorption

Question 18

Which type of intercellular junction acts like a portal, allowing molecules to pass directly from one cell to another?

Accepted Answer

Gap junction

Question 19

Which equation best represents the relationship between the rate of diffusion ($$D) $$across simple squamous epithelium and the thickness of the tissue ($$t$$)?

Accepted Answer

$$D = \frac{k}{t}$$

Question 20

Which of the following is a real-world example of where you would find stratified cuboidal epithelium?

Accepted Answer

Large ducts of sweat glands
