A

MEDULLA

23
Q

The ability to resist damage from foreign substances such as microorganisms, harmful chemicals, and internal threats

A

IMMUNITY

24
Q

nonspecific resistance; the body recognizes and destroys certain foreign substances, but the response to them is the same each time the body is exposed.

A

INNATE IMMUNITY

25
Q

specific immunity; the body recognizes and destroys certain foreign substances, but the response to them improves each time the foreign substance is encountered.

A

ADAPTIVE IMMUNITY

26
Q

ability of adaptive immunity to - recognize a particular substance

A

SPECIFICITY

27
Q

ability of the adaptive immunity to “remember” previous encounters with a particular substance

A

MEMORY

28
Q

Are molecules responsible for many aspects of innate immunity

A

MEDICAL MEDIATOR

29
Q

group of approximately 20 proteins found in plasma

A

COMPLEMENT

30
Q

are proteins that protect the body against viral infections

32
Q
  • movement of WBC toward these chemicals
A

CHEMOTAXIS

33
Q
  • the ingestion and destruction of particles by cells called phagocytes
A

PHAGOCYTOSIS

34
Q

small phagocytic cells that are usually the first cells to enter infected tissues

38
Q

nonmotile cells in CT, esp. near capillaries

confined to a specific area of the body

41
Q

generally distributed throughout the body

42
Q

substances that stimulate adaptive immune responses

A

ADAPTIVE IMMUNITY

43
Q

introduced from outside the body (Ex: bacteria, viruses, chemicals released by microorganisms)

A

FOREIGN ANTIGEN

44
Q

caused by foreign antigens that produce an overreaction of the immune system

A

ALLERGIC REACTION

45
Q

molecules of the body produces to stimulate and immune system response

A

46
Q

results when self- antigens stimulate unwanted destruction of normal tissue

A
