Detailed explanation-1: -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-2: -cellular immunity destroys pathogens inside the cell, whereas humoral immunity destroys pathogens outside the cell.
Detailed explanation-3: -Secreted antibodies bind to antigens on the surfaces of invading pathogens, which flag them for destruction. Humoral immunity is so named because it involves substances found in the humors, or body fluids. There are two types of humoral immunity: active and passive.
Detailed explanation-4: -The key difference between cell mediated and antibody mediated immunity is that cell mediated immunity destroys infectious particles via cell lysis by cytokines, without the production of antibodies, while antibody mediated immunity destroy pathogens by producing specific antibodies against antigens.
Detailed explanation-5: -Humoral and cell-mediated immunity work together to clear pathogens from the body. Humoral immunity is comprised of the body defenses that are mounted by dissolved molecules while cell-mediated immunity uses cells as effectors.
