Immunities

100

Nonself molecules that can elicit an immune response
antigens

100

Describe tissue rejection reaction.
When a recipient's cells recognize cells from a donated tissue as foreign and attempt to destroy the transplanted tissue.

100

Inflammation is characterized by these tissue responses.
Redness, swelling, heat, and pain.

100

The faulty development of this type of cell can cause an autoimmune response.
T-cell

100

The form of immunity that develops after a primary immune response from exposure to a live pathogen.
Naturally acquired active immunity

200

Which vessels have valves?
lymphatic vessels.

200

Why is a donated tissue recognized as foreign.
The donated tissue has antigens that match the antibodies in the recipient's tissue.

200

What causes redness in an inflammatory response?
Increased blood flow due to dilation of blood vessels.

200

This type of infection causes an autoimmune response because the pathogen incorporates the proteins of the body's cell into its own surface.
Viral infection

200

Substance that includes antigens that stimulate an immune response to prevent an infectious disease.
Vaccine

300

Where do T-cells originate and where are they differentiated? (Two answers required)
Red bone marrow, the thymus.

300

Drugs used to reduce the recipient's rejection of transplanted tissue.
Immunosuppressive drugs.

300

What causes swelling in an inflammatory response?
Fluid leaking into tissue spaces due to an increase in capillary permeability.

300

When the immune system fails to distinguish self from nonself and attacks its own self organs and tissues.
Autoimmunity

300

The form of immunity that involves the injection of antibodies and is short-lived.
Artificially acquired passive immunity

400

This duct drains into the left subclavian vein.
Thoracic duct.

400

Chemical that triggers an allergic reaction.
What is an allergen

400

Other than redness, what does an increased blood flow from blood vessel dilation cause?
Heat increase.

400

True or false? A reaction to a nonself antigen that bears close resemblance to a self antigen can cause an autoimmune reaction.
True

400

The form of immunity that occurs as antibodies are passed from mother to fetus and is short-lived.
Naturally acquired passive immunity

500

This duct drains into the right subclavian vein.
Right lymphatic duct.

500

An allergy is an example of this type of reaction, that is an exaggerated immune response to a non-harmful antigen.
Hypersensitivity Reaction.

500

Why does tissue become painful while inflamed?
Increase in pressure on the nerves in the tissue due to the fluid leaked into tissues spaces.

500

This is the name for antibodies that can't distinguish between self and nonself
Autoantibodies

500

The form of immunity that develops after a primary immune response to a weakened virus or pathogen.
Artificially acquired active immunity
