Blood Typing and Transfusions: Saving Lives Through Medical Breakthroughs

The video explores the critical role of blood in the human body, its historical significance, and the development of blood transfusion techniques. It highlights the discovery of blood circulation by William Harvey and the first successful human-to-human blood transfusion by James Blundell. The breakthrough discovery of blood types by Karl Landsteiner in 1901 enabled safer transfusions. Over time, advancements in blood typing and transfusion methods, such as cross-matching and blood banks, have significantly improved medical practices, aiding surgeries, chronic illness management, and more.
