Q: A researcher is studying the rate of diffusion across different epithelial tissues. Which formula should be used to calculate the rate of diffusion ($D$) given surface area ($A$), concentration gradient ($\Delta C$), and membrane thickness ($T$)?

$D = \frac{A \times \Delta C}{T}$

Question 1

Which of the following is NOT a common structural characteristic of epithelial tissue?

Accepted Answer

Cells are widely spaced with abundant extracellular matrix

Question 2

Which type of epithelial tissue is best suited for rapid diffusion and filtration, such as in the alveoli of the lungs?

Accepted Answer

Simple squamous epithelium

Question 3

Endocrine glands differ from exocrine glands in that:

Accepted Answer

Endocrine glands secrete hormones directly into the bloodstream, while exocrine glands secrete products into ducts

Question 4

Which of the following best describes the composition of the extracellular matrix (ECM) in connective tissue?

Accepted Answer

ECM is composed of ground substance and protein fibers

Question 5

Which type of connective tissue fiber is most abundant in connective tissue proper and provides tensile strength?

Accepted Answer

Collagen fibers

Question 6

A patient suffers a deep cut that damages the underlying connective tissue beneath the skin. Which type of connective tissue is most likely involved?

Accepted Answer

Areolar connective tissue

Question 7

Which type of muscle tissue is found in the heart and is responsible for pumping blood throughout the body?

Accepted Answer

Cardiac muscle

Question 8

Which type of muscle tissue is under voluntary control?

Accepted Answer

Skeletal muscle

Question 9

Which of the following is a function of a neuron?

Accepted Answer

Transmission of electrical impulses

Question 10

The basic structure of a neuron includes:

Accepted Answer

Cell body, dendrites, and axon

Question 11

Which of the following is NOT one of the four major types of membranes found in the body?

Accepted Answer

Synovial membrane

Question 12

The thinnest membrane in the body, which produces a wet surface on some of the viscera, is the:

Accepted Answer

Serous membrane

Question 13

Which type of membrane contains a thick lamina propria (connective tissue) and stratified squamous epithelium?

Accepted Answer

Mucous membrane

Question 14

During tissue repair, which of the following is the correct sequence of events?

Accepted Answer

Inflammation, organization, regeneration

Question 15

A patient with chronic bronchitis has excessive mucus production in the respiratory tract. Which type of epithelial cell is primarily responsible for this secretion?

Accepted Answer

Goblet cell

Question 16

Which equation best represents the relationship between tissue repair and cell proliferation rate?

Accepted Answer

$R = k 	imes P$

Question 17

If the basement membrane is damaged in epithelial tissue, which process is most likely to be impaired?

Accepted Answer

Cellular regeneration and repair

Question 18

Which connective tissue type is most likely to be found in tendons, providing strong attachment between muscle and bone?

Accepted Answer

Dense regular connective tissue

Question 19

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

Accepted Answer

It offers multiple layers for protection against mechanical stress

Question 20

A researcher is studying the rate of diffusion across different epithelial tissues. Which formula should be used to calculate the rate of diffusion ($D$) given surface area ($A$), concentration gradient ($\Delta C$), and membrane thickness ($T$)?

Accepted Answer

$D = \frac{A 	imes \Delta C}{T}$
