Question 7

A gland that releases its secretion directly into the bloodstream is classified as:

Accepted Answer

Endocrine

Question 8

Which of the following best explains why epithelial tissues are avascular?

Accepted Answer

They rely on diffusion from underlying connective tissue for nutrients

Question 9

Which cell junction allows ions and small molecules to pass directly from one cell to another, facilitating coordinated activity in tissues such as cardiac muscle?

Accepted Answer

Gap junction

Question 10

A tissue sample from the skin surface shows multiple layers of flat, dead cells filled with protein. Which type of epithelium is this?

Accepted Answer

Stratified squamous keratinized epithelium

Question 11

Which of the following best describes the main function of the basement membrane in epithelial tissues?

Accepted Answer

It attaches the epithelium to underlying connective tissue

Question 12

Accepted Answer

Protection against dehydration and microbes

Question 14

Which of the following is a correct pairing of epithelial tissue and its location?

Accepted Answer

Stratified squamous non-keratinized; esophagus

Question 15

Which of the following equations best represents the relationship between the rate of regeneration ($$R) $$and age ($$A) in $$epithelial tissues, assuming regeneration decreases with age?

Accepted Answer

$$R = k / A$$

Accepted Answer

Stratified cuboidal

Question 20

Which of the following best explains why microvilli are present on the apical surface of some epithelial cells?

Accepted Answer

To increase surface area for absorption
