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 biopsy sample from a patient’s trachea reveals a single layer of cells of varying heights, with nuclei at different levels and cilia on the apical surface. Which type of epithelium is this?

Accepted Answer

Pseudostratified columnar epithelium

Question 3

Which of the following statements about connective tissue is CORRECT?

Accepted Answer

It contains ground substance, fibers, and cells as its main components.

Question 4

A patient suffers a tendon injury. Which type of connective tissue is primarily affected, and what property does this tissue provide?

Accepted Answer

Dense regular connective tissue; provides high tensile strength in one direction

Question 5

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

Accepted Answer

Cartilage is avascular and chondrocytes lose their ability to divide with age.

Question 6

Which mode of secretion involves the entire secretory cell rupturing to release its product, as seen in sebaceous glands?

Accepted Answer

Holocrine

Question 7

A tissue sample shows cells with striations, multiple nuclei, and voluntary control. Which tissue is this, and where is it found?

Accepted Answer

Skeletal muscle; attached to bones

Question 8

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

Accepted Answer

Universal packing material between other tissues

Question 9

Which membrane lines body cavities that open to the exterior and is composed of an epithelial layer overlying loose connective tissue called the lamina propria?

Accepted Answer

Mucous membrane

Question 10

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

Accepted Answer

Fibrosis; impaired contractile function

Question 11

Which of the following cell junctions in epithelial tissue prevents substances from passing between adjacent cells?

Accepted Answer

Tight junctions

Question 12

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

Accepted Answer

Endocrine glands release hormones into interstitial fluid and blood; exocrine glands secrete products onto body surfaces or into cavities.

Question 13

Which connective tissue fiber type is most abundant and provides high tensile strength?

Accepted Answer

Collagen fibers

Question 14

Which of the following tissues has the poorest capacity for regeneration after injury?

Accepted Answer

Cardiac muscle tissue

Question 15

A patient presents with swelling and redness after a minor skin injury. Which step of tissue repair is primarily responsible for these symptoms, and what is the main physiological process involved?

Accepted Answer

Inflammation; increased blood vessel permeability and dilation

Question 16

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

Accepted Answer

Mesoderm

Question 17

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 18

Which of the following is a characteristic of nervous tissue?

Accepted Answer

Composed of neurons and supporting glial cells

Question 19

Which of the following best explains why epithelial tissues are avascular but can still receive nutrients?

Accepted Answer

They are nourished by diffusion from underlying connective tissues.

Question 20

Which of the following is a real-life consequence of excessive scar tissue formation in the heart after a myocardial infarction?

Accepted Answer

Progressive heart failure due to impaired muscle contraction
