Accepted Answer

Facilitation of rapid diffusion of gases

Question 2

A patient presents with a burn that has damaged the outer layer of skin. Which type of epithelial tissue is most likely affected?

Accepted Answer

Stratified squamous epithelium

Question 3

Which characteristic is unique to epithelial tissue compared to other primary tissue types?

Accepted Answer

Has a high regenerative capacity due to frequent mitosis

Question 4

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

Accepted Answer

It provides multiple layers for protection against physical and chemical stress

Question 5

Which equation best represents the relationship between the rate of diffusion ($$R) $$and the thickness of the epithelial layer ($$d) in $$simple squamous epithelium?

Accepted Answer

$$R \propto \frac{1}{d}$$

Question 6

A gland that releases its product directly into the bloodstream is classified as which type of gland?

Accepted Answer

Endocrine gland

Question 7

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

Accepted Answer

Generation of electrical impulses

Question 8

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

Accepted Answer

Compound alveolar gland

Question 9

Which connective tissue cell type is primarily responsible for secreting the extracellular matrix and fibers?

Accepted Answer

Fibroblast

Question 10

A patient with a deficiency in collagen production would most likely experience problems with which property of connective tissue?

Accepted Answer

Tensile strength

Question 11

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

Accepted Answer

Endocrine glands secrete hormones into blood; exocrine glands secrete products onto body surfaces or into cavities

Question 12

Which type of epithelial tissue lines the majority of the gastrointestinal tract and is specialized for absorption and secretion?

Accepted Answer

Simple columnar epithelium

Question 13

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

Question 14

A patient with chronic inflammation has an increased number of which connective tissue cell type that releases histamine and other mediators?

Accepted Answer

Mast cells

Question 15

Which of the following equations best represents the relationship between the viscosity of ground substance ($$\eta) $$and the concentration of glycosaminoglycans ($$[GAG]) in $$connective tissue?

Accepted Answer

$$\eta \propto [GAG]$$

Question 16

Which type of epithelial tissue appears to be stratified but is actually a single layer with nuclei at different heights, often found in the upper respiratory tract?

Accepted Answer

Pseudostratified columnar epithelium

Question 17

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

Accepted Answer

Cartilage is avascular and relies on diffusion for nutrient delivery

Question 18

A patient with a stomach ulcer is experiencing pain due to the breakdown of which protective epithelial secretion?

Accepted Answer

Mucus

Question 19

Which of the following is a correct sequence of tissue organization from simplest to most complex?

Accepted Answer
