The Lymphatic system Tissue Rejection and Allergies Inflammation Autoimmunity Immunities

100

antigens
Nonself molecules that can elicit an immune response

100

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

100

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

100

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

100

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

200

lymphatic vessels.
Which vessels have valves?

200

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

200

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

200

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

200

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

300

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

300

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

300

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

300

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

300

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

400

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

400

What is an allergen
Chemical that triggers an allergic reaction.

400

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

400

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

400

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

500

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

500

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

500

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

500

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

500

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