Question 1

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

Accepted Answer

Simple squamous epithelium

Question 2

A gland that releases its secretions directly into the bloodstream rather than through a duct is classified as which type of gland?

Accepted Answer

Endocrine gland

Question 3

Which of the following best describes the structure and function of adipose tissue?

Accepted Answer

Large round cells filled with lipid droplets; stores energy and cushions organs

Question 4

Which of the following equations correctly represents the relationship between surface area ($$A) $$and volume ($$V) $$for a cuboidal epithelial cell with side length $$l$$?

Accepted Answer

$$A = 6l^2$, V$$ = $$l^3$$

Question 5

A patient presents with a burn that destroys the outer layer of skin. Which type of epithelium is most likely damaged?

Accepted Answer

Stratified squamous epithelium

Question 6

Which connective tissue type is characterized by crisscrossing fibers and scattered fibroblasts, providing support and flexibility to other tissues?

Accepted Answer

Loose (areolar) connective tissue

Question 7

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

Accepted Answer

Exocrine glands have ducts, while endocrine glands are ductless and release products into the bloodstream.

Question 8

Which tissue type is found in the walls of hollow organs such as the intestines and bladder, and is responsible for involuntary movements?

Accepted Answer

Smooth muscle tissue

Question 9

A histological slide shows concentric rings (lamellae) with osteocytes in lacunae connected by canaliculi. What tissue is being observed?

Accepted Answer

Compact bone tissue

Question 10

Which type of epithelial cell is best adapted for absorption and secretion in the digestive tract, often containing goblet cells and microvilli?

Accepted Answer

Simple columnar epithelial cell

Question 11

If the diameter of a spherical adipocyte increases from $$d to$$ $$2d$$, by what factor does its volume increase? (Recall: $$V = \frac{4}{3}\pi r^3$)

Accepted Answer

8

Question 12

Which tissue type contains chondrocytes in lacunae and provides support with flexibility, reducing friction in joints?

Accepted Answer

Cartilage

Question 13

Which of the following best describes the arrangement of collagen fibers in tendons and ligaments?

Accepted Answer

Parallel collagen fibers providing tensile strength in one direction

Question 14

Which muscle tissue type is striated, branched, contains intercalated discs, and is found only in the heart?

Accepted Answer

Cardiac muscle tissue

Question 15

A biopsy from the urinary bladder shows rounded surface cells that stretch to accommodate filling. What type of epithelium is this?

Accepted Answer

Transitional epithelium

Question 16

Which of the following is a function of loose (areolar) connective tissue?

Accepted Answer

Provides support and flexibility to other tissues

Question 17

Which of the following best explains why stratified squamous epithelium is found in areas subject to abrasion, such as the skin and esophagus?

Accepted Answer

Multiple layers of cells provide protection against physical and chemical stress.

Question 18

Which of the following cell shapes is most likely to be found lining kidney tubules, where absorption and secretion are important?

Accepted Answer

Cuboidal

Question 19

A tissue sample shows spindle-shaped cells with a single central nucleus and no striations. Which tissue is this?

Accepted Answer

Smooth muscle tissue

Question 20

Which of the following best describes the process by which an exocrine gland forms from epithelial tissue?

Accepted Answer

A cord of invaginating epithelial cells forms a duct that remains connected to the surface epithelium.
