Question 2

A patient presents with rapid diffusion of oxygen in the lungs. Which tissue type is most likely responsible for this function?

Accepted Answer

Simple squamous epithelium

Question 3

Which equation correctly represents the relationship between surface area ($$A$$), diffusion rate ($$R$$), and concentration gradient ($$\Delta C) in $$epithelial tissue?

Accepted Answer

$$R = A 	imes \Delta C$$

Question 4

Which of the following is a distinguishing characteristic of connective tissue compared to other tissue types?

Accepted Answer

Contains abundant extracellular matrix with scattered cells

Question 5

A biopsy reveals a gland that releases its secretion by exocytosis without losing any part of the cell. Which type of gland is this?

Accepted Answer

Merocrine gland

Question 6

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 7

A patient with jaundice presents with yellowing of the skin. Which pigment is responsible for this coloration?

Accepted Answer

Bilirubin

Question 8

Which of the following best explains the difference between merocrine and apocrine glands?

Accepted Answer

Accepted Answer

Collagen fibers

Question 17

Which of the following best describes the role of melanocytes in the epidermis?

Accepted Answer

Synthesize melanin to protect against UV radiation

Question 18

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

Accepted Answer

Connective tissue

Question 19

Which of the following is a characteristic of transitional epithelium?

Accepted Answer

Allows stretching and recoiling in the urinary bladder

Question 20

Which equation best represents the calculation of body temperature regulation by the skin, where $$Q is $$heat loss, $$A is $$skin surface area, and $$\Delta T is $$temperature difference?
