Organ that filters blood (6)

I believe the answer is:

spleen

(Other definitions for spleen that I've seen before include "Abdominal organ - bad temper" , "Organ associated with ill humour" , "Vent it to show anger" , "Bodily organ associated with bad humour" , "Ill-humour" .)

I've seen this clue in the USA Today.
