Exam 34: The Immune System

A Y-shaped protein that proliferates in response to a specific antigen and recognizes these antigens is

Administering antivenom is a form of active immunity.

In a process called _____,an army of plasma cells and memory cells are produced from properly stimulated B cells.

A vaccine could be prepared against a virus by allowing a patient to breathe viral coat proteins.This primary response would allow for a later,strong secondary immune response to the virus.

A disease-causing agent that does not usually infect and cause disease in a person with a healthy immune system is termed a(n)

If you transfuse type AB blood into a patient with type A blood,the patient will raise antibodies against the B antigen on the donor's blood,but will not raise antibodies against the A antigen.Why not?

A preparation that "teaches" the immune system to recognize a disease-causing agent without actually causing disease is termed a(n)

Lymphatic capillaries help to recycle the contents of blood plasma,thus helping maintain homeostasis in the circulatory system.

T cells direct humoral immunity while B cells govern cell-mediated immune reactions.

B cells and T cells are

A molecule that stimulates an immune system reaction by B cells and T cells is termed a(n)

Why do lymph nodes often become swollen during an infection?

Which of the following is a reason why fever is considered a defense mechanism?

Special cells produced by the immune system that are progeny of properly stimulated B cells and are antibody-producing factories are

If a tumor metastasizes,some of its cells move to another part of the body.Doctors often look in lymph nodes near a tumor for signs of metastasis.Why might cancer cells be found in lymph nodes?

Which can be a target of autoimmune disease but is not considered to be a major part of the immune system itself?

If asked to sort cards into boxes marked "active immunity" and "passive immunity," a card saying what would go into the "passive immunity" box?
