The invention relates to a bag system for the cryopreservation of body fluids, that is blood, bone marrow or umbilical cord blood, the parts of the bag system being sterilized, and separable from one another, wherein liquids which permit and/or assist cryopreservation are located in the bag system and/or may be introduced into the bag system in a sterile form. The bag system, at least, comprising: a device for the direct removal of body fluid (1) from the living body, a region or number of regions for mixing the liquids with the body fluid and/or for storing the mixture of liquids and body fluid, a number of shut-off elements (2) and connecting lines (3) and an inlet element (4) and/or an outlet element (5). The bag system is characterized in that the parts of the bag system, which are connected in a communicating manner to one another by the connecting lines (3), form a closed, sterile system before the bag system is used, and the regions for storing the mixture of liquids and the body fluid are hermetically sealable and separable from one another.

The bag system according to claim 3, wherein the freezing bag comprises one freezing chamber. 5. The bag system according to claim 3, wherein the freezing bag comprises at least two freezing chambers. 6. The bag system according to claim 3, comprising a connection between the mixing bag and the freezing bag by two or more connecting lines, at least one of which carries the mixture of liquids and fluids from the mixing bag to the freezing bag or chamber of the freezing bag, and a second line carries air from the mixture of liquids and fluids in the freezing bag or chamber, back to the emptied mixing bag. 7. The bag system according to claim 3, comprising a connection between the mixing bag and the freezing bag by one connecting line. 8. The bag system according to claim 3, configured for cryopreservation of blood, bone marrow, or umbilical cord blood. 9. The bag system according to claim 1, wherein the regions for storing the mixture of liquids and the body fluid and cells contained therein comprise at least two chambers of a mixing/freezing bag. 10. The bag system according to claim 1, wherein one or more regions for storing the mixture of liquids and body fluid and cells contained therein are formed in at least one of the connecting lines having a plurality of hermetically sealable and separable segments. 11. The bag system according to claim 1, further comprising a fill level indicator affixed to the region for mixing the liquids. 12. The bag system according to claim 1, wherein only the regions that are hermetically sealable and separable from one another for storing the mixture of liquids and body fluid and cells contained therein are configured for storing by cryopreservation. 13. The bag system according to claim 1, wherein the parts of the bag system are configured for only single-use. 14. The bag system according to claim 1, wherein the region for mixing the liquids with the body fluid and the region for storing the mixture of liquids and body fluid and cells contained therein comprise a mixing/freezing bag, and wherein the mixing/freezing bag further comprises a mixing/freezing chamber. 15. The bag system according to claim 1, wherein the region for mixing the liquids with the body fluid and the region for storing the mixture of liquids and body fluid and cells contained therein comprise a mixing/freezing bag, and wherein the mixing/freezing bag further comprises a mixing/freezing chamber and a freezing chamber. 16. A method of preparing body fluids and cells contained therein for long-term storage by cryopreservation in a closed, sterile transportation and storage system, the method comprising: providing a sterile transportation and storage system having parts pre-connected to one another in a liquid-communicating manner to form a the closed, sterile system; introducing body fluid and cells contained therein into the sterile transportation and storage system; holding concentrated cryopreservation liquids until needed in a protected area within the closed system where it will not damage the system; mixing variable volumes of the body fluid with cryopreservation liquids to form a mixture within the closed system, and venting air therefrom within the closed system as necessary to minimize bubbles while maintaining sterility of the mixture; transferring the mixture of cryopreservation liquids and body fluid into a region for storage within the closed transportation and storage system; and hermetically sealing and separating the region or the regions for storing the mixture of cryopreservation liquids and body fluid from the remainder of the closed system. 17.
