An exaggerated or unusual hypersensitivity to foreign protein or other substance?
ANAPHYLAXIS
What cells produce histamine in a type one hypersensitivity reaction?
Basophils Mast cells contain histamine. When they encounter a foreign body, they splay themselves and release histamines which then cause swelling and surround the foreign body so other parts of the immune system can rid the body of the foreign invader. Antihistamines offer much comfort.
Strong reaction of the immune system to a foreign substance?
its an allergy, or an allergic reaction
Immunity that occurs when antibodies come from another source?
If you mean the body is mounting an immune response to foreign antibodies, this can be a case of Type III Hypersensitivity (e.g. serum sickness).
A substance formed by the body in reaction to a perceived foreign substance is?
lymphokine
What is the possible cause of death in a blood transfusion?
These complications may include an acute hemolytic transfusion reaction (AHTR), which is most commonly caused by ABO incompatibility. The patient may complain of pain, difficult breathing, fever and chills, facial flushing, and nausea.
Hypersensitivity to a previous encountered foreign protein?
anaphylaxis
An exaggerated or unusual hypersensitivity to foreign protein or other substance?
ANAPHYLAXIS
What does hypersensitivity pneumonitis refer to?
Hypersensitivity pneumonitis refers to an inflammation of the lungs caused by repeated breathing in of a foreign substance, such an organic dust, a fungus, or a mold.
What is a hemolytic reaction to a blood transfusion?
Most severe type, but rare incompatible blood incompatibility in multiple transfusions. Mostlikely to occurs when transfused red cells react with circulating antibody in the recipient with resultant intravascular hemolysis. When a group O patient is mistakenly transfused with group A, B, or AB blood. Patients receiving a major ABO- incompatible marrow or stem cell transplant with sufficient red cell content will likely develop an acute hemolytic reaction. Symptoms are: fever, chills and fever, the feeling of heat along the vein in which the blood is being transfused, pain in the lumbar region, constricting pain in the chest, tachycardia, hypotension, and hemoglobinemia with subsequent hemoglobinuria and hyperbilirubinemia. Prevention: proper identification of patients, pre-transfusion blood samples and blood components at the same time of transfusion.
What is antigen hypersensitivity?
Hypersensitivity describes associate abnormal or pathologic reaction that's caused by associate immunologic response to perennial exposure to associate matter. Hypersensitivity diseases embrace response diseases, during which immune responses area unit directed against self-antigens, AND diseases that result from uncontrolled or excessive responses to foreign antigens. as a result of these reactions tend to occur against antigens that can't be loose (i.e. self-antigens) and since of regeneration systems intrinsic to numerous aspects of the immunologic response, hypersensitivity diseases tend to manifest as chronic issues.
What is bird keeper's lung?
The technical name for it is Hypersensitivity pneumonitis which is an "inflammation of the lungs due to breathing in a foreign substance, usually certain types of dust, fungus, or molds." https://health.google.com/health/ref/Hypersensitivity+pneumonitis

Basophils Mast cells contain histamine. When they encounter a foreign body, they splay themselves and release histamines which then cause swelling and surround the foreign body so other parts of the immune system can rid the body of the foreign invader. Antihistamines offer much comfort.
What is topotactic reaction?
a reaction where a foreign particle inserts into a host on interface
Strong reaction of the immune system to a foreign substance?

If you mean the body is mounting an immune response to foreign antibodies, this can be a case of Type III Hypersensitivity (e.g. serum sickness).
Is a burn a allergic reaction to heat?
No. An allergic reaction is the body's way of responding to a foreign substance, or an antigen.
