B cells and T cells migrate to secondary lymphoid organs such as lymph nodes and spleen to carry out their immune functions. Here, they encounter antigens, undergo activation, and differentiate into effector cells to mount an immune response.
Immune cells are formed or matured in the bone marrow. This is where stem cells differentiate into various types of immune cells, such as lymphocytes (B cells and T cells) and myeloid cells (neutrophils, macrophages, etc.). Some immune cells, like T cells, undergo further maturation in the thymus.
Following a primary immune response, memory cells are generated from activated B and T cells. These memory cells can recognize the same pathogen if encountered in the future, leading to a faster and stronger secondary immune response. Memory cells are vital for the immune system's ability to provide long-lasting protection against specific pathogens.

B cells activate T cells in the immune response by presenting antigens to T cells. This interaction triggers the T cells to become activated and multiply, leading to a coordinated immune response against the invading pathogen.

T cells activate B cells in the immune response by releasing signaling molecules called cytokines. These cytokines stimulate the B cells to multiply and produce antibodies that target and destroy pathogens. This process helps the immune system to effectively fight off infections.
B cells are activated in the immune response when they encounter a specific antigen that matches their receptors. This triggers the B cells to multiply and differentiate into plasma cells, which produce antibodies to target and neutralize the antigen.
Specific defenses in the immune system include antibodies produced by B cells, which recognize and neutralize specific pathogens. T cells can also destroy infected cells and regulate the immune response. In addition, memory cells are formed after an infection, allowing for a quicker and stronger response upon reinfection.

Epidermal cells that aid in the immune response include melanocytes.
B cells get activated in the immune response process when they encounter a specific antigen that matches their receptors. This triggers the B cell to divide and differentiate into plasma cells, which produce antibodies to target and neutralize the antigen.
