week 3 part 2

Question 1

what is inflammation

Answer 1

an important defense mechanism of the body
- immunovasular response to some form of insult
- cause by a stimulus

Question 2

what is the goal of inflammation

Answer 2

responds to stimuli and restore balance

Question 3

5 cardinal signs of inflammation

Answer 3

pain
heat
redness
swelling
loss of function

Question 4

platelets

Answer 4

release blood clotting proteins at the wound site

Question 5

mast cells

Answer 5

secrete chemical mediators
- vasodilation and increased capillary permeability

Question 6

neutrophils

Answer 6

migrate to the site and secrete factors that kill pathogens, phagocytosis to remove pathogens and debris

Question 7

macrophages

Answer 7

secrete cytokines, phagocytosis to remove pathogens and debris
- increase plasma protein, fever,chemotaxis

Question 8

serous

Answer 8

watery fluid and small amounts of protein and white blood cells

Question 9

fibrinous

Answer 9

-thick and sticky, higher cell and fibrin

Question 10

purulent

Answer 10

thick and yellow higher white blood cells and cell debris

Question 11

hemorrhagic

Answer 11

blood vessels damage

Question 12

resolution

Answer 12

damages cells recover

Question 13

regeneration

Answer 13

damaged cells are a cell type that can
divide by mitosis (e.g. epithelial cells) and can
therefore be replaced by identical cell type.

Question 14

replacement

Answer 14

damaged cells are replaced by connective
tissue (scar tissue). Loss of function in this area.

Question 15

the action of a chemical mediator

Answer 15

• bind to nearby nociceptors
  -vasodilation and increase capillary permeability
• attract immune cels to the site of injury

Question 16

acute inflammation

Answer 16

-fat onset
-followed by anti-inflammatory response
-variable limited
-vascular and exudative
-prominent

Question 17

chronic inflammation

Answer 17

• slow onset
  -no anti-inflammatory component
  -monocytes, macrophages
  -persistent and progressive
  -new connective tissue formation
  -less intense

Question 18

chronic inflammation can result from

Answer 18

• acute inflammation
• low-level exposure
  -defect in cells responsible for mediating inflammation
• inflammatory & biochemical inducers causing oxidative stress

Question 19

nonpharmacologic treatment of chronic inflammation

Answer 19

• nutrition
  -aerobic and resistance exercise
• sleep quality
  -low stress
