Describe the antibody structure

Back 26

Proteins produced in response to antigen; Y shaped; 2 heavy chains and 2 light chains

Front 27

What is an immunoglobulin?

Back 27

Antibodies- globulin proteins involved in immunity (5 of them)

Front 28

Function of the memory B Cell

Back 28

Long-lasting immunity

Front 29

Active Immunity

Back 29

Antibodies that result in response to antigens- natural acquired and active artificial

IgG

Back 35

Largest, most diverse

Virus, bacteria and toxins

Can gross placenta

Front 36

IgE

Back 36

Attaches to basophils and mast cells

Helpful in allergic reactions

Front 37

IgD

Back 37

Surface of B Cells

Binds to antigens in extracellular fluid

Role in activation

Front 38

IgM

Back 38

First secreted into body

Not very effective in fighting, but helps

High concentration until igG increases

Front 39

IgA

Back 39

Glandular secretions- mucus, tears, saliva

Attack pathogens before they gain access to internal tissues

Front 40

The flow of lymph through the Lymphocytes

Back 40

(in) Afferent lymphocytes

Back 42

Lymphatic duct: connect to subclavian vein; right arm and right half of head

Thoracic Duct: left part of head and rest of the body

Front 43

Functions of the Spleen

Back 43

Limited revoir for blood

Front 44

What are pyrogens? What does symptom do the release of them cause to body?

Back 44

Released when the body in invaded (virus); brings up the body temperature
