The Eucharist, also called Holy Sacrifice, considered as a sacrament, is the body and blood of Jesus Christ under the species of bread and wine.
The elements of the Eucharist are the sacramental bread and sacramental wine which are consecrated on an altar and consumed thereafter. Communicants, those who consume the elements, can speak of "receiving the Eucharist" as well as "celebrating the Eucharist".
