Does the immune system have memory cells?
Yes immune system have memory cells. they flow around the blood.
Explain the role of memory cells in the immune system?
Memory cells divide into plasma cells that produce the right antibody.
What are the immune system cells that can recognize and commence an attack on a pathogen that has previously infected the individual?
Memory cells
What kind of cell helps the immune system remember an infection?
Memory B-cells
Does the human heart have memory 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.
Why is it adaptive for memory cells to remain in the immune system after an invasion by pathogens?
As a result of memory cells, on exposure to a second infection by the pathogen the response will be quicker and stronger.
What is the purpose of memory cells?
to remember the intruder for next time so your immune system can work faster.
What do vaccines produce?
Immunity via the production of long lived memory lymphocyte cells in the immune system.
What is the role of memory cells in providing acquired immunity?
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.
What does the statement the immune system has a memory mean?
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.
What are the specific defenses in the immune system?
immune response
How do memory cells differ from effector cells?
Memory cells live longer than effector cells and are responsible for the secondary immune response
