The 17th blessing reads as follows:
רצה השם אלקינו בעמך ישראל ובתפילתם והשב את העבודה לדביר ביתך ואישי ישראל ותפילתם באהבה תקבל ברצון ותהי לרצון תמיד עבודת ישראל עמך... ותחזינה עינינו בשובך לציון ברחמים ברוך אתה השם המחזיר שכינתו לציון:
Favor, God our Lord your nation Israel and their prayers, and return the service to the sanctum of your temple, and the fire offerings of Israel and their prayers with love accept with favor, and may it be for perpetual favor the service of Israel your nation... And may our eyes see your return to Zion with mercy, blessing are you God who returns His Presence to Zion
Every day, in every prayer, we ask for a general restoration of the Temple service, of which the Tamid continual offerings were a daily part. The sprinkling of the morning offering's blood preceded the completion of the lighting of the Candelabra, and the afternoon offering concluded the service for the day, (see Yoma 33a). It is thus included in "the service", and requires no special mention.
"Fire offerings" includes sacrifices that were not routine, such as those outlined in Zevahim 5. They are mentioned broadly to accommodate the disparate obligations of each individual or community.
The Mussaf additional offerings had designated times when they were always to be brought, and as they were not always a part of the service, they were outliers from the general prayer, so they needed specific mention. They also comprise their own separate prayer in our liturgy that does not contain any other prayers, (unlike the first amidah, which also focuses either on personal requests or on the holiness of a special day). This format allows for a more focused meditation.
