Actually they do,
Transubstantiation (Latin: transsubstantiatio; Greek: μετουσίωσις metousiosis) is, according to the teaching of the Catholic Church, "the change of the whole substance of bread into the substance of the Body of Christ and of the whole substance of wine into the substance of his Blood. [...] The Roman Catholic Church teaches that in the Eucharistic offering bread and wine are changed into the body and blood of Christ.
At least when I took communion, I took consecrated wine not blood.
