Question 1

Which of the following best describes the primary function of epithelial tissue in the human body?

Accepted Answer

To cover body surfaces and line internal cavities, providing protection and selective permeability

Question 2

A patient suffers a deep cut that damages the simple squamous epithelium lining their alveoli. Which physiological process is most likely to be impaired?

Accepted Answer

Rapid diffusion of gases such as $$O_2$$ and $$CO_2$$

Question 3

Which of the following equations correctly represents Fick's Law of Diffusion, which is critical for understanding gas exchange across epithelial membranes?

Accepted Answer

$$J = -D \frac{\Delta C}{\Delta x}$$

Question 4

Which connective tissue type is most specialized for storing energy and insulating the body?

Accepted Answer

Adipose tissue

Question 5

A histology slide shows cells embedded in a matrix with visible collagen fibers and no blood vessels. Which tissue is most likely being observed?

Accepted Answer

Cartilage

Question 6

Which of the following best explains why cartilage heals more slowly than bone after injury?

Accepted Answer

Cartilage lacks a direct blood supply, limiting nutrient delivery and waste removal

Question 7

A patient with a genetic defect in collagen synthesis would most likely experience problems in which tissue type?

Accepted Answer

Connective tissue

Question 8

Which of the following is a key distinguishing feature of simple cuboidal epithelium compared to simple squamous epithelium?

Accepted Answer

Simple cuboidal epithelium is specialized for secretion and absorption, while simple squamous is specialized for diffusion

Question 9

Which of the following best describes the function of ground substance in connective tissue?

Accepted Answer

It acts as a medium through which nutrients and other substances can diffuse between blood capillaries and cells

Question 10

A patient presents with swelling and pain in a joint. Synovial membrane inflammation is suspected. Which tissue type is primarily involved in forming the synovial membrane?

Accepted Answer

Loose connective tissue

Question 11

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

Accepted Answer

It consists of cells suspended in a liquid extracellular matrix (plasma)

Question 12

A researcher is studying the rate of diffusion across a membrane. If the surface area ($$A) is $$doubled and the thickness ($$\Delta x) is $$halved, according to Fick's Law, what happens to the rate of diffusion ($$J$$)?

Accepted Answer

It is quadrupled

Question 13

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

Accepted Answer

Transmission of nerve impulses

Question 14

Which of the following scenarios best illustrates the application of the structure-function relationship in anatomy?

Accepted Answer

The thinness of simple squamous epithelium in alveoli allows for efficient gas exchange

Question 15

A tissue sample is observed to have cells that are multinucleated and striated. Which tissue type is most likely being examined?

Accepted Answer

Skeletal muscle

Question 16

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

Accepted Answer

They secrete fibers and ground substance

Question 17

A patient with a burn that destroys the epidermis and underlying connective tissue will have impaired:

Accepted Answer

Protection against pathogens and water loss

Question 18

Which of the following equations correctly represents the calculation of pressure exerted by a force over an area?

Accepted Answer

$$P = \frac{F}{A}$$

Question 19

Which of the following best explains why dense regular connective tissue is well-suited for tendons and ligaments?

Accepted Answer

It has parallel collagen fibers that provide great tensile strength in one direction

Question 20

A patient with a deficiency in ground substance production would most likely experience which of the following symptoms?

Accepted Answer

Reduced diffusion of nutrients and waste between blood and cells
