Spleen
From Tardis Wiki, the free Doctor Who reference
A spleen was an organ.
In the 1890s, a Clockwork Droid scanned the Twelfth Doctor, and listed organs they could harvest, as items on the menu at Mancini's Family Restaurant: liver, spleen, brain stem, eyes, lungs and skin. (TV: Deep Breath)
Alfred took the spleen, kidneys and liver of his first victim with the intention of using them to revive Julius Quilter when he died. (HOMEVID: Unnatural Selection)
