PATHOLOGY

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: -Humoral immunity is named so because it involves substances found in the humors, or body fluids. It contrasts with cell-mediated immunity. Humoral immunity is also referred to as antibody-mediated immunity.

Detailed explanation-3: -Humoral immunity is an aspect of specific immune responses directed at particular antigens. It takes the form of unique antibodies produced by B lymphocytes that have been specifically selected to neutralize the antigen at hand.
