Why Does The Eucharistic Prayer Say ‘Disciples’ Instead of ‘Apostles’ at the Last Supper?

A listener named Jim asks Father Dave about the Last Supper and the Eucharistic Prayer. Jim says, “In the Eucharistic prayer it says, ‘He took bread and gave thanks, broke it and gave it to his disciples.’ Why doesn’t it say apostles? I always envisioned the last supper the way Leonardo da Vinci painted it. Were there more disciples there than the apostles?”
