Pathologic changes in a tissue or organ

Question 19

What are the two types of cellular injury

Answer 19

Reversible and irreversible

Question 20

What is reversible tissue damage

Answer 20

The cell can recover and regain structure and function if the injuring stimulus is removed

Question 21

What is irreversible tissue damage

Answer 21

The cell can not recover is the injuring stimulus is removed. Cell passes a point of no return that leads to cell death (necrosis)

Question 22

What are the three cellular responses to harmful stimuli

Answer 22

Degeneration, necrosis, cell changes

Question 23

What happens during cellular degeneration

Answer 23

Pathological condition that causes cells to change structure and function. Reversible

Question 24

What happens during necrosis cellular injury

Answer 24

Cellular death. Irreversible
Coagulative, liquefactive, caseation, fat

Answer 25

Cell growth, size, and numbers change. Can be reversible or irreversible

Question 26

What are the five signs of inflammation

Answer 26

Redness, heat, pain, swelling, loss of function

Question 27

What are the two types of tissue repair

Answer 27

Organization (replaced by scar tissue) Regeneration (replaced by identical cells)

Question 28

What are the two types of tissue healing

Answer 28

First intention and second intention

Question 29

What is first intention healing

Answer 29

Edges of the wound are close together, no scarring Ex) sutures, skin tape, bandages

Question 31
