Question 1

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

Accepted Answer

Thin and permeable, allowing rapid diffusion of gases

Question 2

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

Accepted Answer

Merocrine

Question 3

Which of the following statements about epithelial tissue is TRUE?

Accepted Answer

Epithelial tissues have a high rate of regeneration and are supported by a basement membrane.

Question 4

A patient has a genetic defect affecting the production of collagen fibers. Which function of connective tissue would be most directly impaired?

Accepted Answer

Binding and supporting organs

Question 5

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

Accepted Answer

It can stretch and recoil as the bladder fills and empties.

Question 6

A multicellular exocrine gland with a branched duct and secretory units shaped like sacs is classified as:

Accepted Answer

Compound alveolar

Question 7

Which of the following is a function of microvilli on the apical surface of epithelial cells?

Accepted Answer

Increasing the surface area for absorption

Question 8

A tissue sample shows a single layer of tall, rectangular cells with nuclei aligned at the same level. Which type of epithelium is this?

Accepted Answer

Simple columnar

Question 9

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

Accepted Answer

Endocrine glands secrete hormones into the bloodstream; exocrine glands release products onto body surfaces or into body cavities via ducts.

Question 10

A biopsy of a gland shows that the entire cell ruptures to release its product. Which type of secretion is this?

Accepted Answer

Holocrine

Question 11

Which of the following equations correctly represents the relationship between the number of layers ($$n) $$and the classification of epithelial tissue?

Accepted Answer

If $$n = 1$$, the epithelium is simple; if $$n \u003e 1$$, it is stratified.

Question 12

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

Accepted Answer

Collagen fibers

Question 13

A patient with a mutation affecting elastin production would most likely have problems with which property of connective tissue?

Accepted Answer

Ability to stretch and recoil

Question 14

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

Accepted Answer

They receive nutrients by diffusion from underlying connective tissue.

Question 15

A tissue sample from the trachea shows cells that appear layered but all touch the basement membrane, with cilia on the apical surface. What is the correct classification?

Accepted Answer

Pseudostratified columnar epithelium

Question 16

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

Accepted Answer

Generation of movement

Question 17

A gland that secretes its product by pinching off a portion of the cell membrane is classified as:

Accepted Answer

Apocrine

Question 18

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

Accepted Answer

Form a fine network to support blood vessels and soft tissues

Question 19

A patient has damage to the basement membrane of their epithelial tissue. Which of the following consequences is most likely?

Accepted Answer

Loss of support and increased risk of tissue detachment

Question 20

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

Accepted Answer

It provides multiple layers for protection against mechanical stress.
