T helper cells
Specific immunity is also known as adaptive immunity or acquired immunity active or passive. There are two types of specific immune responses; humoral and cell mediated. Humoral immunity is mediated by B Lymphocytes that produce antibodies; forms of B lymphocytes are IgG, IgM, IgA, IgE. They primarily attach bacterial invaders Cellular immunity is mediated by T Lymphocytes and combat intracellular infections (such as viruses), monitor cellular disruptions like tumors or foreign tissues, and fight fungal infections.
B lymphocytes are the formed elements most directly responsible for humoral immunity. They produce antibodies that circulate in the bloodstream and bind to antigens, marking them for destruction by other immune cells.
The difference between humoral immunity and cell-mediated immunity is that humoral immunity uses B cells and T cells whereas mediated immunity only uses the T cells. Also humoral immunity provides a defense against antigens and pathogens in body fluids whereas cell-mediated immunity protects from abnormal cells and pathogens inside living cells.
T lymphocytes (T cells) are the cell type that interacts with both humoral and cell-mediated immune pathways. They help orchestrate immune responses by recognizing antigens presented by antigen-presenting cells and signaling other immune cells to either produce antibodies (in the case of B cells) or kill infected cells directly.
Neural control of endocrine glands involves direct stimulation of the glands by nerve impulses, while humoral control involves regulation through circulating hormones in the blood. Neural control typically acts more rapidly and is involved in short-term responses, whereas humoral control is more gradual and regulates long-term processes.

Humoral immunity is effected by antibodies produced by plasma cells toward a specific foreign antigen. Cellular immunity does not directly involve antibodies, but refers to cellular destruction of alien cells/tissues by production of cytotoxins locally, typically the latter are produced by T-lymphocytes and natural killer cells.
B lymphocytes are the formed elements most directly responsible for humoral immunity. They produce antibodies that circulate in the bloodstream and bind to antigens, marking them for destruction by other immune cells.
The cellular system is composed of many classes of T-lymphocytes (white blood cells that detect foreign invaders called antigens).

Antibodies are produced by B lymphocytes as the third line of defense to provide humoral immunity.
