The Lymphatic system
Tissue Rejection and Allergies
Inflammation
Autoimmunity
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
