lymph an immune 2

Pathway of lymphatic tissue

Blood stream, lymphatic vessel, enter rapes by MALT

T cell

Kill other cells

B cell

Plasma cells that produce antibodies

antigens is presentant

Dissolve the bump of WBC, into lympathic tissue to present antigen to T cells. Antigen give is T cells activation

constimulation

Is complete after a second chemical, prevents unneeded immune response

proliferate

Makes copies of itself

Helper

CD4, provides more costimulant in t-cells

cytotoxic

CD8,Combination of antigens, destructive to cells

Binding and activation of B cells

B cells can bind directly to antigen, but are more efficient when oxygen is present to B cells

Differentiated

Turns into memory and plasma cell

Plasma cell

Live for five days and produces millions of antibodies

IgG

80% the most abundant, protection against bacteria and toxic, the mother immunity to the fetus

IgA

Sent 15% found in secretions. Examples are breastmilk, saliva,mucous.

IgE

Rare act as a receptor on Mas and involve with allergies

Primary response (sick)

It take days, IgM moves slow

Secondary response(not sick)

Take hours, IgG goes fast

Naturally acquire active

Antigen is recognized by T cells and B cells

Naturally acquired passive

Transfer of pregnancy(IgG) or breastmilk(IgA)

Artificial acquire active

Introduction of death, antigens to trigger the body into making cytotoxic( T cell memory) and antiBody (B cells vaccination)

Artificial acquire passive

Infection of antibodies

infectious mononucleosis

infection of B lymphocytes with Epstein-Barr virus

lymphoma

cancer of the lymph nodes and lymph organs

systemic lupus erythematosus (SLE)

autoimmune disease in which immune system attacks connective tissue throughout body such as in joints and skin, most common kidney damage
