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 its thin, flat cell structure

Question 2

A biopsy from a patient's esophagus reveals several layers of flattened cells. Which type of epithelial tissue is most likely present?

Accepted Answer

Stratified squamous epithelium

Question 3

Which of the following statements about epithelial tissue is CORRECT?

Accepted Answer

Epithelial tissue is avascular but innervated and has a high rate of regeneration

Question 4

A gland that releases its product by exocytosis without damaging the cell is classified as which type of gland?

Accepted Answer

Merocrine gland

Question 5

Which connective tissue fiber type provides the greatest tensile strength, as described by the equation $$\sigma = \frac{F}{A}$$, where $$\sigma is $$stress, $$F is $$force, and $$A is $$area?

Accepted Answer

Collagen fibers

Question 6

A patient with a torn tendon is most likely to have damage to which type of connective tissue?

Accepted Answer

Dense regular connective tissue

Question 7

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 8

Which of the following is a function of adipose tissue in the human body?

Accepted Answer

Insulation and energy storage

Question 9

A tissue sample shows branched cells with intercalated discs and striations. Which tissue is this?

Accepted Answer

Cardiac muscle

Question 10

Which of the following best describes the role of fibroblasts in connective tissue?

Accepted Answer

They secrete the fibers and ground substance of the extracellular matrix

Question 11

A patient presents with a condition affecting the serous membranes. Which of the following organs is most likely to be directly affected?

Accepted Answer

Heart (pericardium)

Question 12

Which of the following best explains why epithelial tissues are more likely to develop cancer than connective tissues?

Accepted Answer

Epithelial tissues have a high rate of cell division, increasing the chance of mutations

Question 13

Which of the following is TRUE regarding the embryonic origin of tissues?

Accepted Answer

Muscle and connective tissues arise from mesoderm

Question 14

A gland that releases its product by the rupture and death of entire cells is classified as which type of gland?

Accepted Answer

Holocrine gland

Question 15

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

Accepted Answer

To increase surface area for absorption

Question 16

A tissue sample from the urinary bladder shows several layers of cells with dome-shaped surface cells. What type of epithelium is this?

Accepted Answer

Transitional epithelium

Question 17

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

Accepted Answer

Exocrine glands secrete products onto body surfaces or into cavities; endocrine glands secrete hormones directly into the blood

Question 18

Which of the following is a correct sequence of events in tissue repair after injury?

Accepted Answer

Inflammation, organization, regeneration

Question 19

A patient with a genetic defect in the production of adhesion proteins such as fibronectin and laminin would most likely have problems with which aspect of connective tissue?

Accepted Answer

Attachment of cells to the extracellular matrix

Question 20

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

Accepted Answer

Form delicate networks that support soft tissues like lymph nodes
