Primary Immune Response

• What is the primary response?

  When an antigen enters the body for the first time it activates the immune system. This is called the primary response
• Is the primary response fast or slow?

  slow
• Why is the primary response slow?

  Because there are not many B-cells that can make the antibody needed to bind to it
• What does the body eventually do?

  Produce enough of the right antibody to overcome the infection. MEANWHILE the infected person will show symptoms of the disease
• What do B-cells and T-cells do after being exposed to an antigen?

  produce memory cells
• What do the memory t-cells cells do?

  remember the specific antigen and will recognise it a second time around
• what do Memory B-CELLS do?

  Record the specific antibodies needed to bind the antigen
• After the memory cells have been produced, the person is now what?

  immune - their immune system has the ability to respond quickly to a second infection
• how long do the memory cells remaijn in the body for?

  a long time
