Question 1

Which of the following best describes the primary function of epithelial tissue in the human body?

Accepted Answer

It provides protection, absorption, filtration, excretion, secretion, and sensory reception.

Question 2

A tissue sample is prepared for light microscopy. Which step is necessary to ensure the tissue can be properly visualized?

Accepted Answer

The tissue must be preserved with a solvent and cut into thin slices to transmit light.

Question 3

Which characteristic of epithelial tissue allows it to rapidly replace damaged cells?

Accepted Answer

High regenerative capacity due to frequent cell division.

Question 4

A patient has a disorder affecting the basal lamina of their epithelial tissue. Which function is most likely to be compromised?

Accepted Answer

Adhesion of epithelial cells to underlying connective tissue.

Question 5

Which type of epithelial tissue is best suited for rapid diffusion and is found lining the air sacs of the lungs?

Accepted Answer

Simple squamous epithelium

Question 6

Which of the following equations best represents the relationship between surface area ($$A) $$and rate of diffusion ($$R) in $$simple squamous epithelium?

Accepted Answer

$$R = k 	imes A$$

Question 7

Which connective tissue type is most likely to be found in tendons and ligaments, providing high tensile strength?

Accepted Answer

Dense regular connective tissue

Question 8

A histology slide shows cells embedded in a gel-like matrix with thin, highly branched fibers forming a mesh. Which tissue is this most likely to be?

Accepted Answer

Reticular connective tissue

Question 9

Which of the following is TRUE regarding the vascularity of connective tissues?

Accepted Answer

Cartilage is avascular, while bone is highly vascularized.

Question 10

Which cell type is responsible for actively secreting the matrix in bone tissue?

Accepted Answer

Osteoblasts

Question 11

A patient suffers a deep skin wound. Which process is most likely to occur if the damage is extensive and the original tissue cannot be restored?

Accepted Answer

Fibrosis, where connective tissue replaces destroyed tissue

Question 12

Which of the following best explains why epithelial tissue is avascular but still receives nutrients?

Accepted Answer

Nutrients diffuse from underlying connective tissues.

Question 13

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

Accepted Answer

Mucous membrane

Question 14

Which of the following is a function of brown adipose tissue that distinguishes it from white adipose tissue?

Accepted Answer

Brown adipose tissue uses lipid fuels to heat the bloodstream.

Question 15

Which connective tissue fiber type provides high tensile strength and is the most abundant in the human body?

Accepted Answer

Collagen fibers

Question 16

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

Accepted Answer

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

Question 17

A multicellular exocrine gland with both unbranched and branched ducts and both tubular and alveolar secretory units is classified as:

Accepted Answer

Compound tubuloalveolar gland

Question 18

Which embryonic germ layer gives rise to muscle and connective tissues?

Accepted Answer

Mesoderm

Question 19

Which of the following tissues has virtually no functional regenerative capacity?

Accepted Answer

Cardiac muscle and nervous tissue of the brain and spinal cord

Question 20

A patient presents with a disorder affecting the elastic fibers in their arteries. Which physiological process would be most directly impaired?

Accepted Answer

Ability of arteries to stretch and recoil during blood flow
