IMMUNOLOGY

Detailed explanation-1: -Humoral immunity is also called antibody-mediated immunity. With assistance from helper T cells, B cells will differentiate into plasma B cells that can produce antibodies against a specific antigen. The humoral immune system deals with antigens from pathogens that are freely circulating, or outside the infected cells.

Detailed explanation-2: -Type 3 immunity is characterized by the recruitment of neutrophils and the stimulation of epithelial antimicrobial defenses at infection sites. Type 3 immunity is often triggered by extracellular bacteria and fungi and seems to be particularly suited to defend epithelial barriers against these pathogens.

Detailed explanation-3: -Humoral immunity is the first adaptive immune response that functions to rid the body of pathogens in the extracellular spaces such as blood serum and lymph fluid.

Detailed explanation-4: -There are two types of humoral immunity: active and passive.
