Q

goals of inflammation (3)

A

isolate, eliminate, and regenerate

17
Q

a decrease in the diameter of a vessel

A

vasoconstriction

18
Q

movement of white blood cells to an area of inflammation in response to the release of chemical mediators by neutrophils, monocytes, and injured tissues

A

chemotaxis

19
Q

process in which white blood cells (neutrophils, monocytes, and macrophages) engulf and destroy microorganisms, other foreign antigens, and cell debris

A

phagocytosis

20
Q

a localized accumulation of pus

A

abscess

21
Q

an open sore or lesion of skin or mucous membrane accompanied by sloughing of inflamed, necrotic tissue

A

ulcer

22
Q

blister-like elevation of skin containing serous fluid

A

vesicle

23
Q

an abscess or pustular infection of a sweat gland or hair follicle

A

furuncle (boil)

24
Q

several communicating boils of the skin and subcutaneous tissues that produce and discharge pus

A

carbuncle

25
Q

a small elevation of the skin containing pus

A

pustule

26
Q

protein-rich fluid containing white blood cells, especially neutrophils, and cell debris produced during inflammation commonly caused by infection with pyogenic bacteria

A

pus

27
Q

any fluid released from the body with a high concentration of protein, cells, or solid debris oozing through the tissues into a cavity or to the surface

A

exudate

28
Q

exudate which contains blood

A

hemorrhagic

29
Q

primarily composed of pus resulting from
infections

A

purulent (suppurative)

30
Q

-first cells to enter the site of injury
-able to phagocytize
-produce chemicals to attract other cells
-short lived

A

neutrophils

31
Q

-cells that kill bacteria
-involved in allergic reactions and parasitic infections
-present for longer than neutrophils
-present in chronic inflammation

A

eosinophils

32
Q

cells which release histamine

A

basophils (in blood) / mast cells (in tissue)

33
Q

histamine causes _____

A

vasodilation

34
Q

-cells that enter site of injury within 3-4 days
-able to phagocytize
-present in chronic inflammation

A

macrophages

35
Q

-cells that have surface proteins specific for antigens
-can “remember” a previously encountered antigen

A

lymphocytes

36
Q

the termination of the inflammatory response with the affected part returning to its normal state

A

resolution

37
Q

-damaged cells are replaced with identical new cells
-not all tissue has this capacity
-certain diseases interfere with this process

A

regeneration

38
Q

the restoration of damaged tissue by the growth of new, healthy cells not necessarily of the same type as the original tissue

A

repair

39
Q

a form of repaired tissue consisting of connective tissue (no blood vessels, hair follicles, oil/sweat glands or nerve endings)

A

scar (cicatrix)
