Accepted Answer

Protection against physical and chemical injury

Question 2

A patient presents with a wound that is healing primarily by regeneration. Which tissue type is most likely involved in this process?

Accepted Answer

Epithelial tissue

Question 3

Which of the following best describes the structure and function of tight junctions (zonula occludens) in epithelial tissue?

Accepted Answer

They prevent movement of materials between adjacent cells

Question 4

Which equation correctly represents the relationship between surface area ($$A) $$and the rate of diffusion ($$R) $$across a simple squamous epithelium?

Accepted Answer

$$R = k 	imes A 	imes (C_1$ - C_2$)$$

Question 5

Which of the following glands is classified as a unicellular exocrine gland and is commonly found in the lining of the respiratory and intestinal tracts?

Accepted Answer

Goblet cell

Question 6

A biopsy of tissue reveals cells joined by desmosomes. Which of the following is a likely function of this tissue?

Accepted Answer

Strong mechanical attachment between cells

Question 7

Which type of epithelial tissue is best suited for diffusion and filtration, and is found lining the alveoli of the lungs and blood vessels?

Accepted Answer

Simple squamous epithelium

Question 8

Which of the following best explains why inflammation is a necessary response to tissue injury?

Accepted Answer

It increases the permeability of capillaries, allowing immune cells to reach the site of injury

Question 9

A patient with chronic bronchitis has excessive mucus production in the respiratory tract. Which cell type is most responsible for this symptom?

Accepted Answer

Goblet cell

Question 10

Which of the following is a characteristic feature of connective tissue that distinguishes it from epithelial tissue?

Accepted Answer

Cells are separated by abundant extracellular matrix

Question 11

Which of the following equations best represents the relationship between the number of cell layers ($$n) $$and the rate of regeneration ($$R) in $$stratified epithelium?

Accepted Answer

$$R = k \div n$$

Question 12

Which type of membrane lines body cavities that open to the exterior, such as the digestive and respiratory tracts?

Accepted Answer

Mucous membrane

Question 13

A patient has a genetic defect in gap junction proteins. Which physiological process would be most directly affected?

Accepted Answer

Intercellular communication

Question 14

Which of the following best describes the function of microvilli on the apical surface of epithelial cells?

Accepted Answer

Increase surface area for absorption

Question 15

Which tissue type is most likely to undergo fibrosis rather than regeneration after injury?

Accepted Answer

Cardiac muscle tissue

Question 16

Which of the following is a function of serous membranes?

Accepted Answer

Production of serous fluid to reduce friction between organs

Question 17

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

Accepted Answer

Endocrine glands secrete hormones directly into the bloodstream; exocrine glands secrete products onto body surfaces or into body cavities

Question 18

A patient with a burn injury to the skin is at increased risk for infection. Which property of the cutaneous membrane is most responsible for this protective function?

Accepted Answer

Physical barrier formed by stratified squamous epithelium

Question 19

Which of the following best explains why simple cuboidal epithelium is found in kidney tubules?

Accepted Answer

It allows for secretion and absorption

Question 20

Which of the following is a correct sequence of events in tissue repair after injury?

Accepted Answer

Inflammation → Organization → Regeneration or Fibrosis
