T cells apex
or
B cells
Memory B cells are only active during a specific immune response. They are a type of white blood cell that "remembers" previous pathogens the immune system has encountered and can quickly respond to future infections by producing specific antibodies.

Active immunity will generally occur when a person is exposed to pathogens. This will happen when a disease develops as a result of agents that cause diseases.
•Monocytes are responsible for: --Many specific and nonspecific phagocytic and killing functions --Processing foreign molecules and presenting them to lymphocytes --Secreting biologically active compounds that assist, mediate, attract, and inhibit immune cells and reactions
the production of antibodies against a specific agent by the immune system.
Naturally acquired active immunity is the type of resistance that is acquired from developing a disease. Naturally acquired active immunity leaves the person immune from developing the disease again in the future.
An immune response
Langerhans cells are the specific cells in the skin that are involved in the immune response. They function as antigen-presenting cells and help to initiate immune reactions by presenting antigens to other immune cells.
= not responsible for If one is immune from liability then that person cannot be held responsible for the reason that person has immunity from.
The thymus is most active during childhood and adolescence. It plays a crucial role in the development and maturation of T cells, which are important for immune function. As we age, the thymus gradually shrinks and becomes less active.
Humans can develop active immunity naturally through exposure to a pathogen, which triggers an immune response and the production of antibodies. Artificially, active immunity can be induced through vaccination by administering weakened or inactivated forms of a pathogen, prompting the immune system to produce memory cells for future protection against that specific pathogen.
An active antibody is a Y-shaped protein molecule that is produced by the immune system in response to the presence of a foreign substance (antigen) in the body. The two arms of the Y-shaped antibody can bind to specific antigens, marking them for destruction by other immune system cells.
