What purpose do memory B and T cells serve?
Memory immune B cells are important in the secondary immune response - a process which has adapted to confer continued protection to the body from previously encountered pathogens or other invading substances. Memory B cells are the reason why we do not get the same infection twice. In a healthy individual, one infection is enough to stimulate the memory B cells to produce anitbodies to counteract the pathogen (or antigen). Upon concomitant infection, the body is already 'trained' to combat the infection. This is why memory B calls are so important to the proper functioning of the immune system.
What do white blood cells release to destroy pathogens?
Antibodies are released by B-lymphocytes (one of thekinds of white blood cells)
Antigens cause immature B cells to?
When a B cell detects an antigen, it will engulf it and then display it on its cell surface with an MHC molcule. This antigen/MHC combination is then detected by a T cell - which will send signalling molcules to B cells to multiply and mature into plasma cells (which create antibodies against the antigen) and memory B cells (which 'remember' the antigen for next time).They become plasma cells
Does a T cell engulf pathogens and distroy them?
usually the cell engulfment is donr by B cells the T cells produces cytokinesis and cleaves the antigens
The body's main defense against pathogens is the?
the body's second line of defense against pathogens is the B cells.
Do memory B cells remember pathogens?
Yes.First exposure: Sensitizing dose - elicits no symptomsMemory B cells are produced (now have the memory)Small amount of IgE antibodies are producedMast cells and basophils activatedSecond exposure: Allergens (those things that cause an allergy) bind to memory B cells.B cells produce large amounts of IgE antibodies (high titer)IgE bind to mast and basophil cellsRelease chemical mediators
Cells that remember how to make antibodies for a specific pathogen?
this is called memory B cells
What kind of cell helps the immune system remember an infection?
Memory B-cells
What do B and T lymphocytes do?
T cells (Thymus cells) and B cells (bone cells).The function of T cells and B cells is to recognize specific "non-self" antigens, during a process known as antigen presentation. Once they have identified an invader, the cells generate specific responses that are tailored to maximally eliminate specific pathogens or pathogen infected cells. B cells respond to pathogens by producing large quantities of antibodies which then neutralize foreign objects like bacteria and viruses. In response to pathogens some T cells, called T helper cells, produce cytokines that direct the immune response while other T cells, called cytotoxic T cells, produce toxic granules that contain powerful enzymes which induce the death of pathogen infected cells.Following activation, B cells and T cells leave a lasting legacy of the antigens they have encountered, in the form of memory cells. Throughout the lifetime of an animal these memory cells will "remember" each specific pathogen encountered, and are able to mount a strong and rapid response if the pathogen is detected again.

What does b cells create against pathogens?
They transform themselves to lots of plasma cells, which create antibodies to fight against the pathogens.
When b cells secrete antibodies does it fight against endogenous or exogenous pathogens?
exogenous pathogens.
What type of cells does your body make to remember microbes the invade your body?
the memory cell, that is the reproduction of the B-cell

How are B-cells involved in your specific defence?
B-cells produces antibodies that target specific pathogens so t-cells can then recognize it and consume it.
What is bodies second line of defense against pathogens?
the body's second line of defense against pathogens is the B cells.
What do the T-cells do?
If im correct, helper t-cells activate: b-cells that mark viruses and make them stick together, killer t-cells --which attack macrophages and infected cells, and memory b-cells, which remember how to stop viruses, this i believe is called active immunity
