Answer
Exam answer
The RED CROSS SOCIETY (Red Cross).
Explanation
The Red Cross maintains BLOOD BANKS, where donated blood is collected, tested, grouped and stored under refrigeration until needed.
WHY BLOOD MUST BE STORED RATHER THAN TAKEN ON DEMAND: a patient losing blood cannot wait while a matching donor is found and tested. Storage makes transfusion immediate.
Blood can be kept for only a limited period — about 35 to 42 days — because red cells have a lifespan of roughly 120 days and deteriorate outside the body. That is why blood banks need continuous donation rather than a one-off supply.
