In this episode, we trace the fascinating history of blood transfusions, from risky animal experiments and failed milk injections to the discovery of blood types and disease screening. You'll hear how blood transfusions became one of medicine's safest procedures, why researchers are still debating exactly when patients need them, and what innovations could make blood easier to store, transport, and use in emergency situations including the military battlefield.
