Yes immune system have memory cells. they flow around the blood.
As a result of memory cells, on exposure to a second infection by the pathogen the response will be quicker and stronger.
White cells play important roles in the immune system.
"Memory B cells" of the immune system stay in your body after an infection to enable quick immune responses to the disease-causing organism (antigen) if later exposed again. Antibodies are proteins made by the type of white blood cells called B-cells/"plasma cells" in response to the presence of antigens. The antibodies attach to the B-cells as "B-cell Receptors" to activate them, and can cause them to become either the memory B-cells or more plasma cells.
memory cells
Both B cells and T cells
Memory cells divide into plasma cells that produce the right antibody.
Lymphocytes that stay in the blood after an infection is gone
Memory cells
Memory B-cells
Memory cells, or T cells, are part of the immune system and carried in the blood stream. Due to the fact that they are carried in blood, the heart does help pump them, but it does not "have" memory cells of its own.
As a result of memory cells, on exposure to a second infection by the pathogen the response will be quicker and stronger.
to remember the intruder for next time so your immune system can work faster.
Immunity via the production of long lived memory lymphocyte cells in the immune system.
The idea of immunisation is that you expose the immune system to the pathogen, ennabling it to recognise the pathogen and produce mature memory Helper T cells. This means that upon its second exposure the immune system is activated faster and more efficiently, allowing the immune system to kill off the pathogen quicker. In some cases antibodies are produced that can neutralise toxins, preventing their damaging effects. If memory T cells were not produced then the immune system would have to re-learn how to fight a pathogen every time.
your memory cells remember how to fight off an infection, so if you get it again then your antibodies remember how to fight it off.
immune response
Memory cells live longer than effector cells and are responsible for the secondary immune response
