exudate contains both serum and blood, thin and watery

A

serosanguinous

33

release of pyrogens which causes body temp to rise

A

fever

38
Q

inflammatory process consumes more than what the body can manufacture

A

leukocytosis vs leukopenia

39
Q

presence of bacteria in the blood stream

A

bacteremia

40
Q

presence of bacteria and its toxins in the blood stream

A

septicemia

41
Q

presence of toxins within the bloodstream (no bacteria)

A

toxemia

42
Q

contraction and distortion of an organ

A

scarring

43
Q

union of opposing bands of inflammatory tissue, 2 bands of tissue that are not normally joined together (may be thin like plastic wrap or thick)

A

adhesions

44
Q

focal inflammatory lesion in which the tissue reaction primarily consists of chronic inflammatory cells

A

granulomatous inflammation

45
Q

consists of necrotic core surrounded by zones of chronic inflammatory cells

A

granuloma

46
Q

inflammatory phase

A

initial response to injury, 1-4 days post injury, redness, swelling, heat, and pain, platelet and and leukocyte aggravation, exudative

47
Q

proliferative phase

A

day 4-42, increased rate of collagen synthesis by fibroblasts, granulation tissue, gain tensile strength

48
Q

remodeling phase

A

6 wks-1 year, intermolecular cross-linking of collagen, increased tensile strength, scare flattens

49
Q

tissue undergoes restructuring by cells that belong there

A

regeneration

50
Q

replacement of destroyed tissue by connective tissue

A

repair

51
Q

vascular connective tissue (super red, fleshy tissue that forms when a wound is healing)

A

granulation tissue

52
Q

aka primary wound healing, wound by approximation or wounds created and closed in operating room, clean fresh wounds, wound is treated by irrigation and debridement, treated within 24 hours following injury

A

healing by first intention

53
Q

aka secondary wound healing, wound left open and allowed to close through epithelialization, no surgical intervention, slower healing

A

healing by second intention

54
Q

aka tertiary wound healing, managing wounds that are heavily contaminated, not previously treated

A

healing by third intention

55
Q
