PATHOLOGY

Detailed explanation-1: -Antibodies are made to attach to certain proteins on the surface of an invading organism, called antigens. By sticking to these antigens, antibodies block the invader’s ability to replicate, and enter cells, thereby rendering the invader useless.

Detailed explanation-2: -Antibodies are protective proteins produced by your immune system. They attach to antigens (foreign substances)-such as bacteria, fungi, viruses and toxins-and remove them from your body.

Detailed explanation-3: -The antigens and antibodies combine by a process called agglutination. It is the fundamental reaction in the body by which the body is protected from complex foreign molecules, such as pathogens and their chemical toxins.

Detailed explanation-4: -Antibodies attach to a specific antigen and make it easier for the immune cells to destroy the antigen. T lymphocytes attack antigens directly and help control the immune response. They also release chemicals, known as cytokines, which control the entire immune response.
