Accepted Answer

Rapid diffusion of gases

Question 2

A patient presents with a wound that heals by the replacement of destroyed tissue with the same kind of tissue, restoring original function. Which process is primarily responsible for this outcome?

Accepted Answer

Regeneration

Question 3

Which of the following statements about epithelial tissue is TRUE?

Accepted Answer

Epithelial tissue is supported by connective tissue and is avascular but innervated.

Question 4

Which type of connective tissue is most likely to be found in tendons and ligaments, and why?

Accepted Answer

Dense regular connective tissue, because its parallel collagen fibers provide high tensile strength in one direction.

Question 5

A gland that releases its product by exocytosis without damaging the secretory cell is classified as which type?

Accepted Answer

Merocrine

Question 6

Which of the following best explains why cartilage injuries heal slowly in adults?

Accepted Answer

Cartilage is avascular and chondrocytes lose their ability to divide with age.

Question 7

Which of the following cell types is responsible for maintaining the matrix in mature bone tissue?

Accepted Answer

Osteocytes

Question 8

A tissue sample shows cells with an apical surface covered in cilia and a basal surface attached to a basement membrane. The cells appear to be in multiple layers, but all touch the basement membrane. What type of epithelium is this?

Accepted Answer

Pseudostratified columnar epithelium

Question 9

Which of the following best describes the main function of reticular connective tissue?

Accepted Answer

Forms a supportive stroma for blood cells in lymph nodes, spleen, and bone marrow

Question 10

Which membrane type lines body cavities that open to the exterior and is composed of an epithelial layer over a loose connective tissue called the lamina propria?

Accepted Answer

Mucous membrane

Question 11

A patient with a heart attack develops scar tissue in the myocardium. Which process is primarily responsible for this, and what is a likely consequence?

Accepted Answer

Fibrosis; impaired contractile function of the heart

Question 12

Which of the following is a characteristic of all connective tissues?

Accepted Answer

They arise from mesenchyme and contain an extracellular matrix.

Question 13

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

Accepted Answer

Endocrine glands are ductless and secrete hormones into the blood; exocrine glands secrete products onto body surfaces or into cavities via ducts.

Question 14

Which of the following tissues has the poorest capacity for regeneration after injury?

Accepted Answer

Cardiac muscle tissue

Question 15

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

Accepted Answer

It is composed of keratinized stratified squamous epithelium attached to a thick layer of connective tissue.

Question 16

Which of the following cell types is responsible for initiating local inflammatory responses in connective tissue?

Accepted Answer

Mast cells

Question 17

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 18

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

Accepted Answer

They secrete ground substance and matrix fibers.

Question 19

Which of the following is a function of smooth muscle tissue?

Accepted Answer

Involuntary movement in the walls of hollow organs

Question 20

Which embryonic germ layer gives rise to nervous tissue?

Accepted Answer
