MICROANATOMY

Detailed explanation-1: -antibody, also called immunoglobulin, a protective protein produced by the immune system in response to the presence of a foreign substance, called an antigen. Antibodies recognize and latch onto antigens in order to remove them from the body.

Detailed explanation-2: -They are created by the immune system to fight germs and foreign substances. Antibodies can quickly detect germs and other potentially harmful substances, and then attach to them. This neutralizes the “intruders” and attracts other immune system cells to help. Antibodies are produced by the B lymphocytes.

Detailed explanation-3: -Lymphocytes. They create antibodies to fight against bacteria, viruses, and other potentially harmful invaders. Neutrophils.

Detailed explanation-4: -To enter cells, viruses and intracellular bacteria bind to specific molecules on the target cell surface. Antibodies that bind to the pathogen can prevent this and are said to neutralize the pathogen. Neutralization by antibodies is also important in preventing bacterial toxins from entering cells.
