Detailed explanation-1: -Active Immunity results when exposure to a disease organism triggers the immune system to produce antibodies to that disease. Active immunity can be acquired through natural immunity or vaccine-induced immunity.
Detailed explanation-2: -Active immunity utilizes cytotoxic T lymphocytes, TH1, TH2 cells, and activated B cells to target infections from multiple angles. CTLs destroy infected cells, and the immunoglobulins produced by B cells target antigens in the bloodstream to bind and prevent them from reaching their target cells.
Detailed explanation-3: -B cells create antibodies. B lymphocytes, also called B cells, create a type of protein called an antibody. These antibodies bind to pathogens or to foreign substances, such as toxins, to neutralize them. For example, an antibody can bind to a virus, which prevents it from entering a normal cell and causing infection.
Detailed explanation-4: -B lymphocytes (or B cells) are each programmed to make one specific antibody. When a B cell comes across its triggering antigen it gives rise to many large cells known as plasma cells. Each plasma cell is essentially a factory for producing antibody. An antibody matches an antigen much like a key matches a lock.
