In short: While we often claim a shared humanity, our biology tells a more complex story. This video explores the fundamental differences between the four major blood types and the science of why certain types can mix while others cannot.
Natalie S. Hodge examines the four primary blood types—A, B, AB, and O. The lesson investigates the underlying mechanisms that dictate compatibility between these varieties, explaining why some blood transfusions are safe while others are not.
