Q

Give three (3) more functions of the lymph capillaries aside from the weave between tissue cells etc.

A

Walls overlap to form flaplike minivalves, capillaries are anchored to connective tissue by filaments, and higher pressure on the inside closes minivalves

37
Q

Highly specific resistance to disease is ______

A

Immunity

38
Q

Mechanical barriers to pathogens

A

Innate body defenses

39
Q

Innate body defenses include:

A
  • Body surface coverings (intact skin and mucous membranes)
  • Specialized human cells
  • Chemicals produces by the body
40
Q

Provide the first line of defense against invasion of microorganisms

A

Surface membrane barriers

40
Q

First line of defense against invasion of microorganisms

A

Surface membrane barriers

41
Q

Second line of defense

A

Cells and chemicals (Natural killer cells and phagocytes)

42
Q

_____ lyse (burst) and kill cancer cells and virus-infected cells.

A

Natural killer (NK) cells

43
Q

NK cells release chemicals called _____ and ______ to degrade target cell contents

A

perforin and granzymes

44
Q

Triggered when body tissues are injured

A

Inflammatory response

45
Q

Four most common indicators (cardinal signs) of acute inflammation

A

RHPS

  • Redness
  • Heat
  • Pain
  • Swelling (edema)
46
Q

Damaged cells release inflammatory chemicals called ____ and ____

A

Histamine and Kinin

47
Q

Functions of the inflammatory response

A
  • Prevents spread of damaging agents
  • Disposes of cell debris and pathogen thru phagocytosis
  • Sets the stage for repair
48
Q

Most important types of antimicrobial proteins

A
  • Complement proteins
  • Interferon
49
Q

What does MAC mean?

A

Membrane Attack Complex

50
Q

Small proteins secreted by virus-infected cells

A

Interferon

50
Q

Small proteins secreted by virus-infected cells

A

Interferon

51
Q

Complement proteins are 20 ______

A

plasma proteins

52
Q

Abnormally high body temperature

A

Fever

53
Q

________ regulates body temperature at 37°C

A

Hypothalamus

54
Q

The hypothalamus thermostat can be reset higher by _______ (secreted by WBC)

A

pyrogens

55
Q

Why does our body get hotter when something is wrong with the body?

A
  • It is because high temperature inibits the release of iron and zinc (needed by bacteria) from the liver and spleen. Also, fever increases the speed of repair
56
Q

Third line of defense

A

Adaptive body defenses

57
Q

Three aspects of adaptive defense

A
  1. Antigen-specific
  2. Systemic
  3. Memory
58
Q

Two arms of the adative body defense system

A
  1. Humoral immunity - antibody-mediated immunity
  2. Cellular immunity - cell-mediated immunity
59
Q

Any substance capable of exciting the immune system and provoking an immune response

A

Antigens
