Question 1

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

Accepted Answer

Passage of materials by passive diffusion and filtration

Question 2

A tissue sample from the trachea reveals cells of varying heights, all attached to the basement membrane, with cilia and goblet cells present. What is the most likely tissue type?

Accepted Answer

Pseudostratified columnar epithelium

Question 3

Which connective tissue type is most responsible for resisting tension in multiple directions and is found in the dermis of the skin?

Accepted Answer

Dense irregular connective tissue

Question 4

Which of the following cell junctions is primarily responsible for preventing molecules from passing between adjacent epithelial cells?

Accepted Answer

Tight junctions

Question 5

A patient suffers a deep cut that heals with scar tissue rather than the original tissue type. This process is best described as:

Accepted Answer

Fibrosis

Question 6

Which of the following best explains why cartilage heals poorly after injury?

Accepted Answer

Cartilage lacks blood vessels and nutrients must diffuse through the matrix

Question 7

Which tissue type is specialized for storing energy, insulating against heat loss, and supporting organs?

Accepted Answer

Adipose tissue

Question 8

Which of the following is a property of transitional epithelium that makes it uniquely suited for the urinary bladder?

Accepted Answer

It allows for distension and stretching as the bladder fills

Question 9

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

Accepted Answer

Increasing surface area for absorption

Question 10

A biopsy reveals a tissue with multiple layers of cells, with the apical layer being flat and the basal layers cuboidal. This tissue is most likely:

Accepted Answer

Stratified squamous epithelium

Question 11

Which of the following connective tissue fibers is most responsible for providing tensile strength and resisting stretching?

Accepted Answer

Collagen fibers

Question 12

Which type of gland secretes hormones directly into the surrounding tissue fluid and lacks ducts?

Accepted Answer

Endocrine gland

Question 13

Which of the following best describes the main function of reticular connective tissue in the spleen?

Accepted Answer

Formation of a soft internal skeleton (stroma) that supports other cell types

Question 14

Which muscle tissue type is characterized by branching cells, striations, and intercalated discs?

Accepted Answer

Cardiac muscle

Question 15

Which of the following best explains why blood is considered a connective tissue?

Accepted Answer

It consists of cells surrounded by a nonliving matrix (plasma)

Question 16

A patient with a genetic defect in the protein elastin would most likely have problems with which tissue function?

Accepted Answer

Recoil of tissues after stretching, such as in arteries

Question 17

Which of the following is TRUE regarding the regenerative capacity of tissues?

Accepted Answer

Cartilage has a weak capacity for regeneration

Question 18

Which of the following best describes the function of gap junctions in cardiac muscle tissue?

Accepted Answer

Allowing direct passage of ions and small molecules for coordinated contraction

Question 19

Which of the following is a key difference between simple and stratified epithelia?

Accepted Answer

Stratified epithelia have multiple layers and are primarily protective

Question 20

Which of the following best describes the role of the basal lamina in epithelial tissue?

Accepted Answer

It acts as a selective filter and scaffolding for regenerating cells
