OG exemplary drawing
 
1. A blood component collection set associated with an apheresis system comprising:
a needle configured to draw whole blood from a-doner whole blood source;
a first tube having a lumen fluidly associated with the needle, the first tube being configured to move the whole blood through the lumen after a draw pump engaged with the first tube draws the whole blood from the whole blood source;
a blood component collection bladder configured to be inserted into a centrifuge and fluidly associated with the first tube, the blood component collection bladder being configured to separate the whole blood into a first blood component including plasma and a second blood component;
a second tube fluidly associated with the blood component collection bladder, the second tube being configured to move the first blood component from the blood component collection bladder; and
a collection container fluidly associated with the second tube that extracts the first blood component from the apheresis system, wherein
the second tube is further configured to move the first blood component back towards the blood component collection bladder through the second tube to move at least the second blood component from the blood component collection bladder back into the whole blood source.
