Answer:

The ABO blood group system was discovered in the year 1900 by Karl Landsteiner. Jan Janský is credited with the first classification of blood into the four types (A, B, AB, and O) in 1907, which remains in use today. In 1907 the first blood transfusion was performed that used the ABO system to predict compatibility.

Explanation:

Realdo Columbo (1515–1559) confirmed the pulmonary circulation on vivisection. He also discovered that the heart's four valves permitted flow of blood in one direction only: from the right ventricle to the lungs, back to the left ventricle, and from there to the aorta. William Harvey was born on 1 April 1578.
