Blood donation is when a person voluntarily gives blood, which can be used for blood transfusions or to make certain drugs. Blood banks store this blood. The blood can be used to help the victims of accidents, for example
This day was first launched on June 14, 2004, in Johannesburg, South Africa. The date was selected in honor of Karl Landsteiner’s birthday. He discovered and classified the A, B, and O blood groups at the turn of the 20th century. It’s because of his discovery that doctors became able to transfuse blood from one patient to another, and thus save countless lives.
Lived 1868 — 1943.
Karl Landsteiner revolutionized medicine when, in 1900-1901, he identified three major human blood types: A, B, and O, which led to safe blood transfusions and millions of lives saved. He also suggested the use of blood types to assist in police enquiries. Thirty years later, he was awarded the Nobel Prize in Physiology or Medicine for his discovery of the ABO blood group system.
