Q

2nd line defense nonsoecific

A

Phagocytosis

Inflammation fever- histamine released causes redness, heat, swelling, pain. Causes vasodilation

Pyrexia aka fever
Protective proteins- interferon- works against viruses
Complement proteins- circukates inactive .pokes holes in bacteria
Nk cells - works against cancer and microves

17
Q

Circukatee inactively there just in case we need it . Pokes hole in bacteria

A

Complement bacteria

18
Q

Whennus lymohadema most commonly seen

A

Node discection. Radiationx removal lymohatif system caused by tx of cancer

19
Q

Cells work against cancer and mucrobes

A

Natural born killer cells

20
Q

Lymphatic tissue located in mucosa partially encapsulated lymph nodes in throat area

A

Tonsils

21
Q

Appendix contains what?

A

Lymohatic nodules

22
Q

Largest lymohatic organ in body

A

Spleen

23
Q

What dies soleen fikter

A

Blood not lymph fluid

24
Q

Requires activation by specific antigen has memory for future attacks

  1. antibody mediated
  2. Cell mediated
A

Specific aka adaptive immunity

25
Q

Immunity based 9n activitybof b lymphocytes

A

Antibody mediated

26
Q

4 types T cells

A
  1. Killer cells cytoxic cells
  2. Helper t cells
  3. Supressor t cells(once battle over)
  4. Memory t cell (remembers antigen for future attacks)
27
Q

What percentage are t cells

A

70-80 %

28
Q

This immune cell response doesnt involve antibodies. Involves activation of phagocytes antigrn soecific cytotoxix t lymphocytes

A

Cell mediated

29
Q

Immunoglobulins aka name

A

Anti bodies

30
Q

Why are immunoglobukine aka antibodies made

A

In response to something specific

31
Q

What does antibody mediated immunity involve

A 
Protects via antibodies
Protects via extra cellular  pathogens
B cells b lymphocytes
Basis of artificial immunity
The antibody remains circukating in system.
B cells make 2 copies
32
Q

What does cell mediated protect against

A

Protects cells by directing against intercellukar pathogens aka macrophages
Some cancers
Tissue rejection
Antigen presentation- body sees something not native to me so it activates t cells

33
Q

What are protective proteins called

A

Interferons

34
Q

What does antibody mediated immunity circulate

A

Produces circukating antibodies in response to presence of foreign substance and recognize substance upon renewed exposure

35
Q

What does white pulp do

A

Cleans blood the same as lymph nodes clean lymph fluid. Lymphatic tissue and lumphocytes

36
Q

Info 9n red pulp

A

Venus sinuses filled w blood
Blood cleansed as flows through
Microorganisms destroyed by leaukocytes
Stores blood esoecialoy platelets

37
Q 
Lymphatic organ that is where  t cells matures
In mediastinum
Decreases in size and function
Home of lymphocytes
Some inactive and some active 
Active in immune response 
Secretes hormones
A

Thymus gland

38
Q

Formation of antibodies to substances usually not recognized as foreign ex. Peanut butter

A

Allergic reactions

39
Q

2 types allergic reactions

A

Delayed onse- allergy takes abiut 48 hrs to develop

Immediate reactions-need epipen. Pollen drugs

40
Q

Organ transplant issues?

A

Tissue or organ rejection
