Humoral immunity is mediated by antibodies.
B cells are the primary cells involved in humoral immunity, and they indirectly produce this immunity through the secretion of antibodies. When B cells encounter an antigen, they can differentiate into plasma cells, which produce specific antibodies that bind to the antigen, neutralizing it or marking it for destruction. Additionally, helper T cells play a crucial role in activating B cells, enhancing their ability to produce antibodies and thus facilitating the humoral immune response.
The adaptive defense system consists of two main arms: humoral immunity and cell-mediated immunity. Humoral immunity is characterized by the production of antibodies by B cells, which target and neutralize pathogens in the body fluids. In contrast, cell-mediated immunity involves T cells that directly attack infected or cancerous cells and orchestrate the immune response. Together, these two arms provide a tailored defense against specific pathogens and ensure long-lasting immunity through memory cells.
Passive humoral immunity is the transfer of pre-formed antibodies from one individual to another. This can occur naturally, such as when a newborn receives antibodies from their mother through breastfeeding, or artificially through the administration of antibody-containing products like immunoglobulin injections. Passive immunity provides immediate protection but is temporary because the transferred antibodies eventually degrade in the recipient's body.
Cell-mediated immunity. T cells play a key role in cell-mediated immunity by directly attacking infected cells or coordinating the immune response.
This process is known as antibody production or humoral immune response. B cells are activated by antigens, differentiate into plasma cells, and secrete antibodies to target and neutralize specific pathogens. This response is important for the body's ability to defend against infections and develop immunity.
humoral immunity
Actually acquired immunity consists of "humoral immunity" and "cell mediated immunity. Acquired immunity is the same with adaptive immunity, it is when the antibodies are produced within the bodies after the exposure of pathogen. Humoral immunity secreted antibodies while cell mediated immunity involves in production of T lymphocytes.

humoral immunity
Humoral immunity primarily produces antibodies, which are proteins secreted by B cells in response to antigens. These antibodies circulate in the bloodstream and bind to specific pathogens, neutralizing them or marking them for destruction by other immune cells. Additionally, humoral immunity also involves the production of memory B cells, which provide long-term immunity by remembering past infections.
Humoral Immunity- acquired immunity in which the role of circulating antibodies is predominant. Natural Immunity- the resistance of the normal animal to infection
