Roman Catholic AnswerThe Blessed Sacrament is placed on the altar, held in a Luna, placed in a Monstrance on the altar.
It is customary to reverence the altar (which means while facing the altar, stand "at attention", and then make a slight bow of the head) when a Catholic visiting the inside of a Catholic church passes an altar where Holy Mass has been celebrated, but where the Blessed Sacrament is not presently reserved. (When passing an altar or a tabernacle where the Blessed Sacrament is reserved, Catholics customarily genuflect instead.)
An altar is actually called "the altar", although if there are many altars in a Church, they may be called by a specific name, like the main altar, the high altar, the side altar, the Blessed Virgin Mary altar, the altar of repose, the Blessed Sacrament altar, the St. Joseph altar, etc.

To venerate means "respect"... At the entrance of Mass, the priest bows to the ALTAR, genuflects to the Blessed Sacrament (different forms - respect vs. adoration) ascends the steps of the altar, places both hands on the altar, bends to kiss the altar, rises... begins Mass. Should a deacon assist... at the entrance the deacon bows/genuflects... kisses the altar, but does not place his hands upon the altar.
The priest comes into the Church, genuflects to the Blessed Sacrament, reverences the altar, and goes to his chair.
In a special sanctuary on the Altar. There may be several in larger churches.
The six chief parts of Christian doctrine are based on the teachings of Martin Luther and include: the Ten Commandments, the Apostles' Creed, the Lord's Prayer, the Sacrament of Holy Baptism, the Office of the Keys and Confession, and the Sacrament of the Altar (Holy Communion). These parts serve as a foundational framework for understanding the teachings and beliefs of Christianity.
Marriage was defined as a sacrament around the 12th century - the same century when clegy celibacy in the western church became mandatory and women were no longer ordained for service at the altar (yes, the Church did ordain women as bishops, priests and as deacons)
