What gives a rise to plasma cells during primary immune response?
B-cells differentiate into plasma cells and memory cells in the primary immune response. The memory cells then produce antibodies.In the secondary, memory cells created in the primary differentiate into plasma cells and secrete antibodies immediately. This is a much faster response, explaining why the secondary response causes a person to suffer less or unnoticeably.
Development of a secondary immune response is based on populations of?
memory cells
What are the 2 main parts of the immune system?
Primary versus Secondary Immune ResponseThe primary immune response occurs the first time that the immune system comes in contact with the antigen. During this time the immune system has to learn to recognize antigen and how to make antibody against it and eventually gain immunological memory. This primary response takes time (about two weeks) and during this time the person experiences signs of illness. IgM antibodies are the hallmark of a new infection because they are the first antibodies made when a person is exposed to an antigen for the first time. After the body learns to make IgM antibodies, it will start making IgG antibodies to the antigen.The secondary immune response occurs the second time (3rd, 4th, etc.) the person is exposed to the same antigen. At this point immunological memory has been established and the immune system can start making antibodies immediately. The antigen usually is killed within minutes and the person is not aware that he/she was attacked. The antibodies in this response are IgG and IgA or (in the case of allergy IgE).
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.
Does the immune system have memory cells?
Yes immune system have memory cells. they flow around the blood.
What gives a rise to plasma cells during primary immune response?
B-cells differentiate into plasma cells and memory cells in the primary immune response. The memory cells then produce antibodies.In the secondary, memory cells created in the primary differentiate into plasma cells and secrete antibodies immediately. This is a much faster response, explaining why the secondary response causes a person to suffer less or unnoticeably.
The process by which the body remembers previous infections and produces antibodies more quickly if that infection is seen again?
Memory B cells are formed following primary infection and are important in antibody-mediated immune response in the case of re-infection. The response is very rapid. This is also known as a secondary immune response.
What distinguishes the secondary immune response from the primary immune response?
the secondary immune response is faster and stronger than the first. the primary response also takes a few days to react with the antigen whereas the secondary immune response reacts faster to an antigen.
Which cell types initiate a secondary immune response?
Memory cells
Development of a secondary immune response is based on populations of?
memory cells
The immune cell that allows for subsequent recognition of an antigen resulting in a secondary response is called an?
The immune cell that allows for subsequent recognition of an antigen resulting in a secondary response is called a memory cell. Memory cells are small, long-lived lymphocytes.
What cells are responsible for making the secondary immune response work?
A hallmark of immune reponses is memory for specific antigens that have triggered immune responses in the past. Immunological memory is due to the presence of a long- lasting antibodies and very long-lived lymphocytes that arise during proliferation and differentiation of antigen-stimulated B cells anf T cells. Every new encounter with the same anigen results in a rapid proliferation of memory cells. Therefore the antibody titer is far more greater than during a primary response and consist mainly of IgG antibodies. This secondary response.
How do memory cells differ from effector cells?
Memory cells live longer than effector cells and are responsible for the secondary immune response

Would lack of memory B cells for a particular antigen impact the primary or secondary humoral response?
secondary humoral response.
Why does an inactivated vaccine induce only a humoral response?
T-cell memory is very important for long-lasting immunity, because T-cells control both humoral and cell mediated immunity.When the immune system recognizes a foreign antigen for the first time, an immune response is produced. When T cells are involved, immunological T-cell memory is produced. When the body encounters same antigen subsequently, a stronger immune response is produced. This is because of existing immunological memory against that antigen. Further antigenic stimulus increases the immune response. First antigenic stimulus is "priming"whereas subsequent stimuli are "booster". This is the principle of active immunization.
