Although man has existed on earth for millions of years, most of the research on human physiology has been done during the last 200 years. The first discovery of blood circulation in the human body was made in 18 by William Harvey, an English physiologist. After Harvey explained that blood was supplied to the heart and brain, the door was opened to transfuse blood from the human body.

In 1912, Richard Lower of Oxford University succeeded in transfusing one dog's blood into another. According to this method, a French physician named Jean-Baptiste Denis Lower was killed by a man who took blood from a sheep and transfused it into the body of a sick man. In 1913, James Blundell of London used syringes in a human body for blood donation at Guys Hospital. In the 18th century, a woman suffering from postpartum hemorrhage had a blood transfusion, but in most cases, the blood transfusions were followed by fatal reactions.

In 1900, Carl Lansteiner identified the blood group and saved it from the fetal reaction of the blood. American surgeon George Washington Krill is believed to have first transfused blood from the body of one blood donor to the body of another recipient. This technique became popular during the First World War, which took place between 1918 and 1917, when a physician named Edward Lindman punctured and developed the technique of taking blood even outside the operating room.
