Detailed explanation-1: -Humoral immunity works by a mechanism requiring the substances found in body fluids, i.e. humor. It’s also called “antibody-mediated immunity” as antibody production is one of the notable features of this immunity development.
Detailed explanation-2: -The major difference between humoral and cell-mediated immunity is that humoral immunity produces antigen-specific antibodies, whereas cell-mediated immunity does not.
Detailed explanation-3: -Antibody-mediated immunity involves the activation of B cells and secretion of antibodies when in contact with a pathogen. When exposed to the chemicals released by activated helper T cells, a sensitized B cell divides, producing daughter cells that differentiate into memory B cells and plasma cells.
