So when a B Cell receptor connects to a turkey drumstick, a big chunk of antigen, it swallows it and processes it inside itself, just like a Dendritic Cell would. It slices the big chunk of meat up into dozens or even hundreds of tiny sausage parts, all the size of wieners. And these tiny parts are then put into MHC molecules (hot dog buns) on the surface of the B Cell. Basically, a B Cell takes a complex antigen and turns it into many processed, simpler pieces that are then presented to the Helper T Cell.
