discovery of blood types
In the 17th century, after Harvey discovered blood circulation, humans began to try blood transfusions. In 1667, the French philosopher Denis and the surgeon Emmerez transfused 250 ml of sheep blood to a patient. This was the first blood transfusion recorded in human history. Of course, the result was unsuccessful and the patient died.
In 1829, British doctor Brundle completed the first human-to-human blood transfusion experiment. However, the results of subsequent trials were still disappointing. Most patients died and only a few recovered. What was the reason?
