Question 1

Which of the following best describes the main function of simple squamous epithelium in the alveoli of the lungs?

Accepted Answer

Diffusion of gases due to thin, single cell layer

Question 2

A biopsy reveals a tissue with multiple layers of flat, dead, and keratinized cells. Where is this tissue most likely found?

Accepted Answer

Epidermis of the skin

Question 3

Which of the following is a characteristic feature of pseudostratified columnar epithelium?

Accepted Answer

Single layer of cells with nuclei at varying levels, all attached to the basement membrane

Question 4

A patient suffers a tendon injury. Which type of connective tissue is primarily affected?

Accepted Answer

Dense regular connective tissue

Question 5

Which of the following best explains why cartilage heals more slowly than bone after injury?

Accepted Answer

Cartilage is avascular, so nutrients and cells required for repair diffuse slowly

Question 6

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

Accepted Answer

Absorption of nutrients

Question 7

A gland that releases its secretion directly into the bloodstream without using a duct is classified as:

Accepted Answer

Endocrine gland

Question 8

Which type of cell junction is primarily responsible for preventing the passage of substances between adjacent epithelial cells in the intestinal lining?

Accepted Answer

Tight junctions

Question 9

A tissue sample shows cells with striations, multiple nuclei per cell, and voluntary control. Which type of muscle tissue is this?

Accepted Answer

Skeletal muscle

Question 10

Which of the following best describes the function of neuroglia in nervous tissue?

Accepted Answer

Support, protect, and nourish neurons

Question 11

Which of the following equations best represents the relationship between the surface area ($$A) $$and volume ($$V) of a $$cube-shaped cell with side length $$l$$?

Accepted Answer

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

Question 12

A patient presents with a burn that destroys the epidermis and damages the underlying connective tissue. Which two main tissue types are affected?

Accepted Answer

Epithelial and connective

Question 13

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

Accepted Answer

It provides a thick, protective barrier due to multiple cell layers

Question 14

Which connective tissue component is responsible for resisting tensile (pulling) forces?

Accepted Answer

Collagen fibers

Question 15

A histology slide shows a single layer of tall, column-shaped cells with nuclei aligned near the base. Which tissue is this most likely to be?

Accepted Answer

Simple columnar epithelium

Question 16

Which of the following best describes the function of areolar connective tissue?

Accepted Answer

Binds and supports other tissues, providing elasticity and cushioning

Question 17

A patient with a genetic defect in gap junctions would most likely experience problems in which physiological process?

Accepted Answer

Cell-to-cell communication and coordinated contraction in cardiac muscle

Question 18

Which of the following best explains why transitional epithelium is found in the urinary bladder?

Accepted Answer

It can stretch and change shape to accommodate fluctuating volumes of urine

Question 19

Which of the following is a correct pairing of connective tissue type and its primary function?

Accepted Answer

Dense irregular connective tissue – resists tension in multiple directions

Question 20

A patient is diagnosed with a disease that destroys the myelin sheath in nervous tissue. Which cell type is most likely affected?

Accepted Answer

Neuroglia
