Imminity System Primer -EX2

Question 1

Antigen

Answer 1

Molecule that cause immune response

Question 2

Epitope

Answer 2

Binding site for antigen

Question 3

Pathogen

Answer 3

Disease causing agent

Question 4

Tolerance

Answer 4

Ability to distinguish self or foreign antigen

Depends on MHC

Question 5

Major Histocompatibility Complex

MHC

Answer 5

Act as code tags for what to attack

Code on chromosome 6

Question 6

Classes of MHC

Answer 6

MHC I

MHC II

Question 7

MHC I

Answer 7

Found on surface of all cells.

Acts like billboard for intercellular activity

Question 8

MHC II

Answer 8

Made by antigen presenting cell APC

Known as macrophages, shows extra cellular abnormalities

Phagocytes

Lymphocytes

Question 10

Phagocytes-types

Answer 10

Neutrophils

Macrophages

Question 11

Lymphocytes

-types

Answer 11

B lymphocytes

T lymphocytes

Question 12

B lymphocytes

Answer 12

Split into plasma cell and memory cells

Question 13

T lymphocytes

-def

Answer 13

Responsible for cell to cell response

Question 14

T lymphocytes subgroups

Answer 14

Helper T- cd4

Memory T

Cytoxic-cd8/killer t

Question 15

Helper T(CD4)

Answer 15

Recognize MHC II and direct response (commander)

Question 16

Memory T

Answer 16

Long term retention and Help quicker response next time

Question 17

Cytotoxic (CD8/ killer T)

Answer 17

Recognize MHC I and destroys infected cells through perforation

Question 18

FAB (fragment antigen binding)

Answer 18

Where B cells attach to epitopes

Question 19

How antigens destroy

Answer 19

Opsonization- attract IR cells to pathogen and prepare it to get eat

Agglutination-clump cells

Activate complement -membrane attack complex (MAC)
