Q: Which of the following equations best represents the relationship between tissue repair outcomes?

$$\text{Tissue Repair Outcome} = \text{Regeneration} + \text{Fibrosis}$$

Question 1

Which of the following best describes the main function of simple squamous epithelium in the human body?

Accepted Answer

Filtration and exchange of substances, such as in the air sacs of the lungs

Question 2

A patient suffers a severe burn that destroys the epidermis and underlying connective tissue. Which tissue characteristic will most likely affect the healing process in this patient?

Accepted Answer

The avascularity of epithelial tissue, which slows nutrient delivery

Question 3

Which of the following statements about connective tissue is CORRECT?

Accepted Answer

Connective tissue originates from embryonic mesenchyme and contains an extensive extracellular matrix

Question 4

A biopsy reveals a tissue sample with ciliated cells and numerous mucus-secreting cells lining the upper respiratory tract. Which epithelial type is most likely present?

Accepted Answer

Pseudostratified columnar epithelium

Question 5

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

Accepted Answer

Cartilage is avascular, so nutrients and cells required for repair arrive slowly

Question 6

A gland that releases its product by exocytosis without losing cellular material is classified as:

Accepted Answer

Merocrine

Question 7

Which connective tissue type is best suited for resisting tension from multiple directions, such as in the dermis of the skin?

Accepted Answer

Dense irregular connective tissue

Question 8

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

Accepted Answer

Binding and support of organs

Question 9

Which of the following equations best represents the relationship between tissue repair outcomes?

Accepted Answer

$$	ext{Tissue Repair Outcome} = 	ext{Regeneration} + 	ext{Fibrosis}$$

Question 10

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

Accepted Answer

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

Question 11

Which muscle tissue type is responsible for voluntary movement and is characterized by long, cylindrical, striated cells?

Accepted Answer

Skeletal muscle

Question 12

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

Accepted Answer

Transitional epithelium

Question 13

Which of the following best describes the role 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 14

Which of the following is a correct pairing of connective tissue cell type and its mature form?

Accepted Answer

Chondroblast – Chondrocyte

Question 15

A patient with a wound that heals primarily by fibrosis rather than regeneration is most likely to experience which outcome?

Accepted Answer

Formation of scar tissue with possible loss of function

Question 16

Which membrane type lines body cavities that open to the exterior and is kept moist by secretions?

Accepted Answer

Mucous membrane

Question 17

Which of the following best explains why brown fat is important in infants?

Accepted Answer

It generates body heat through non-shivering thermogenesis

Question 18

Which of the following equations correctly represents the relationship between the three primary germ layers and tissue development?

Accepted Answer

$$	ext{Epithelium} = 	ext{Ectoderm} + 	ext{Mesoderm} + 	ext{Endoderm}$$

Question 19

Which of the following best describes the function of neurons in nervous tissue?

Accepted Answer

They receive and transmit electrical impulses for body regulation

Question 20

A tissue sample is stained and observed under a microscope. The cells are arranged in a single layer of tall, closely packed cells with microvilli and mucus-producing cells. Which tissue is this most likely to be?

Accepted Answer

Simple columnar epithelium
