Question

Quizplus · Accepted Answer

An antigen is a substance that triggers an immune response in the body. When an antigen enters the body, specialized cells recognize it as foreign and initiate an immune response to fight it off. This can involve the production of antibodies, which are proteins that specifically target and bind to the antigen, marking it for destruction by immune cells. Immunoglobulins are a type of antibody, but not all substances that provoke an immune response are immunoglobulins. Antihistamines are medications used to treat allergic reactions by blocking the effects of histamine, a chemical released during an immune response. Allapath is not a scientific term related to immunology.
