Immune System Review - Part Two

Which of the following is NOT part of innate immunity?

• Inflammation

• Complement proteins

• Phagocytosis

• Antibodies

Which organ is where lymphocytes mature into T cells?

• Bone marrow

• Thymus

• Spleen

• Lymph nodes

The location in the body where lymphocytes mature into B cells is the

• thymus

• blood

• lymph nodes

• bone marrow

Any substance that causes your immune system to produce antibodies is a(n)

• interferon

• Toxin

• immunoglobulin

• Antigen

Antibodies are also called

• antigens

• immunoglobulins

• serum

• complement

Which antibody is primarily involved in allergic reactions?

• IgA

• IgD

• IgE

• IgM

Also known as an immunoglobulin (Ig), this is a large, Y-shaped protein produced by plasma cells that are used by the immune system to identify and neutralize pathogens such as bacteria and viruses.

• B cells

• T cells

• Antibody

• Antigen

A type of T cell that destroys infected cells is a:

• cytotoxic T cell

• helper T cell

• memory T cell

• suppressor T cell

What do memory B cells do?

• Kills the virus

• Eats the virus

• Patrol the area and make the immune system work faster next time.

• Makes antibodies

Agglutination is when

• antibodies bind to an antigen and activate complement

• antibodies bind to an antigen and enhance phagocytosis

• antibodies bind to an antigen and stop the antigen from binding to host cells

• antibodies bind to antigens and cause them to clump together
