MCQ IN MEDICINE

Detailed explanation-1: -Antibodies. Antibodies help the body to fight microbes or the toxins (poisons) they produce. They do this by recognising substances called antigens on the surface of the microbe, or in the chemicals they produce, which mark the microbe or toxin as being foreign. The antibodies then mark these antigens for destruction.

Detailed explanation-2: -Antigens are markers that tell your body that something is foreign. Your immune cells make antibodies to recognize and destroy harmful antigens. In fact, you can think of antigens as antibody generators. Antibodies are very specific to the antigens they recognize and destroy.

Detailed explanation-3: -Your immune system protects you from infection with several layers of defense. A key component is a type of white blood cell called a B cell. These cells are responsible for making antibodies.
