Which was most likely an effect on society that resulted from improvements in blood handling during world war 1 and 2?

Improvements in blood handling during World War I and II significantly advanced medical practices, leading to increased survival rates for injured soldiers and civilians. This progress fostered greater public trust in medical institutions and paved the way for the establishment of blood banks and transfusion services in peacetime. As a result, the experience gained during the wars ultimately contributed to the development of modern transfusion medicine, influencing healthcare practices and emergency response protocols in society as a whole.
