What did the aztcs use to sacrifice people?

The Aztecs favorite [ and preffered] method of a sacrifice was taking the catured warrior, etc, to the top of one of there pyramids. there the high priest would rip out there heart , cut of there head , place it one a rack, and kick the corpse down the pyramids stairwell. gross huh? in some cases hat was left of the captured warrior at the botttom of the stairwell was eaten.
