Baptism is the first sacrement. It is the sacrement signifying our entry into the Catholic Church. Baptism forgives us of Original sin and personal sins commited before Baptism. Baptism is usually received as soon as possible after birth. In Baptism the priest immerses the infant in water and baptises him in the name of the Father, the Son and the Holy Spirit.
During the sacrement of Confession we confess our sins to a priest who takes the place of Christ during the sacrement. The priest absolves us of our sins, offers us advice on overcoming such temptations and usually gives us a short penence to say or do.
The sacrement of the Holy Eucharist is the memorial of Jesus Christ's Passover - His suffering, death and ressurection made present in this sacrement. During the mass the priest consecrates bread and wine which become the body and blood of Christ. When we receive the Holy Eucharist we receive the body and blood of Christ under the appearence of bread and wine. In doing so we abide in Christ and Christ abides in us. Children usually receive their First Holy Communion at around the age of 7.
Confirmation is a sacrement that perfects Baptismal grace. During confirmation the Holy Spirit strengtens our bond with the church, associates us more closely with the Church's mission and helps us to bear witness to our faith more closely in word and deed. Confirmation is usually received at around the age of 13.
Holy Orders is the sacrement by which a man is ordained a priest or deacon.
Matrimony is the sacrement during which a man and a women undertake a holy vow before God and are joined together in marriage.
The sacrement of Annointing of the sick confers a special grace on those who have grave illness or old age and are in danger of dying.

The sacrement of Annointing of the sick has as its effects the forgiveness of sins if the person was not able to obtain it through the sacrement of confession.
