no choices this is for a DBA tomorrow. i have to be uo in a few hours for work, do my DBA during my break and go back to work so i just really need to get this done
FLVS? if so there is a whole section of humoral immunity. I had biology

yes but i dont know mypassword. i have it saved on my computer and im not home to use it
brb going to get my notes
you da best bae!
what module was this?
Activated when antibodies recognize and bind to antigens on the surface of an invading pathogen.
B cells circulate through the blood stream, patrolling for invading pathogens. B cells have antibodies embedded on their surface, and the unique shape of the antibodies enables them to recognize and attach to one specific type of antigen.
Once a B cell’s antibody binds to a pathogen’s antigen, T cells stimulate the B cell to grow and divide rapidly. This division produces two types of B cells: plasma cells and memory B cells.
Plasma cells produce and release antibodies into the bloodstream to be carried throughout the body. The antibodies bind to any corresponding antigens that they encounter. A healthy adult can produce around 10 billion different types of antibodies, each able to bind to a different type of antigen. When this binding occurs, the plasma cells act as signals to proteins and cells that attack and destroy the invading pathogen.
The plasma cells die once an infection is gone, but some memory B cells remain. If the same type of pathogen ever enters the body again in the future, the memory cells are able to respond more rapidly that the B cells in the primary response. Memory B cells can produce new plasma cells very quickly, which then bind to the pathogens and signal for their destruction.
found it ;P
omg you are a life saver!!!!!
hah i just got that achievement LOL
i barely know you but i already love you! @whatdoesthismean
