If you mean, Did they eat bleeding, gory flesh, tearing into his muscles and shedding his blood on the floor? the answer is No.
Jesus said, holding a piece of bread in his hands, “This is my body.” Similarly with the chalice of wine, which he said, “This is the chalice of my blood.”
The flesh and blood Jesus gave them in the sacrament was the same flesh and blood physically present to their eyes, ears, and touch. It was given to them in such a manner that they could obey his command to eat and drink in a non-bloody, non-horrific way.
Since this was done at the Passover, where eating the lamb was essential to the ritual under the Old Covenant, and since Jesus was the Lamb about to be sacrificed (He carried his cross at the same hour as the lambs were being slaughtered all over Jerusalem.) it makes perfect sense that eating the Lamb would be an essential part of the ritual in the New Covenant. St. John in particular emphasizes that Jesus is replacing the old Passover with a new Passover, the old lamb with the Lamb of God (himself), the old sacrament with a new sacrament.
The Old Covenant existed precisely to prefigure and prepare the Jewish mind for the New Covenant.
