Detailed explanation-1: -This type of response, called humoral immunity, is active mainly against toxins and free pathogens (those not ingested by phagocytes) in body fluids.

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: -The humoral innate immune response consists of multiple components, including the naturally occurring antibodies (NAb), pentraxins and the complement and contact cascades. As soluble, plasma components, these innate proteins provide key elements in the prevention and control of disease.

Detailed explanation-4: -Innate immunity also comes in a protein chemical form, called innate humoral immunity. Examples include the body’s complement system and substances called interferon and interleukin-1 (which causes fever). If an antigen gets past these barriers, it is attacked and destroyed by other parts of the immune system.
