Accepted Answer

Rapid diffusion of gases

Question 2

A patient suffers a severe burn that destroys the epidermis. Which property of epithelial tissue allows for the regeneration of the skin?

Accepted Answer

High regenerative capacity

Question 3

Which of the following is a distinguishing characteristic of epithelial tissue that allows it to form effective barriers?

Accepted Answer

Presence of tight junctions and desmosomes

Question 4

A biopsy of a gland reveals cells that accumulate their products until they rupture, releasing both the product and cell fragments. Which type of secretion is this?

Accepted Answer

Holocrine

Question 5

Which connective tissue fiber type is most responsible for providing high tensile strength to tendons?

Accepted Answer

Collagen fibers

Question 6

A histological sample shows a single layer of tall, closely packed cells with microvilli and goblet cells. Where is this tissue most likely found?

Accepted Answer

Lining of the small intestine

Question 7

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

Accepted Answer

It is avascular and relies on diffusion for nutrient supply

Question 8

A patient with liver damage is unable to produce sufficient albumin, a protein found in blood plasma. Which tissue type is primarily responsible for the synthesis of albumin?

Accepted Answer

Connective tissue (blood)

Question 9

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

Accepted Answer

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

Question 10

A tissue sample from the urinary bladder shows cells that change shape when stretched. Which type of epithelium is this?

Accepted Answer

Transitional epithelium

Question 11

Which of the following equations best represents the relationship between the components of ground substance in connective tissue?

Accepted Answer

$$Ground\ substance = Interstitial\ fluid + Cell\ adhesion\ proteins + Proteoglycans$$

Question 12

A patient presents with a wound that heals with scar tissue rather than restoration of the original tissue. Which process is primarily responsible for this outcome?

Accepted Answer

Fibrosis

Question 13

Which of the following best explains why the skin is classified as a cutaneous membrane?

Accepted Answer

It is a dry membrane consisting of keratinized stratified squamous epithelium attached to connective tissue

Question 14

Which of the following tissues has the greatest regenerative capacity after injury?

Accepted Answer

Epithelial tissue

Question 15

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

Accepted Answer

Tensile strength and support in connective tissues

Question 16

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

Accepted Answer

They secrete ground substance and fibers to form the extracellular matrix

Question 17

A histological section shows a tissue with thick bundles of collagen fibers running in multiple directions. This tissue is most likely found in:

Accepted Answer

Dermis of the skin

Question 18

Which of the following best explains why areolar connective tissue is considered the 'universal packing material' of the body?

Accepted Answer

It supports and binds other tissues, holds body fluids, and defends against infection

Question 19

A patient with a blocked lymphatic vessel develops swelling in the lower limb. Which connective tissue component is most responsible for holding excess interstitial fluid?

Accepted Answer

Areolar connective tissue

Question 20

Which of the following best describes the process that occurs first during tissue repair after injury?

Accepted Answer
