The human embryo's first blood cells arise in the yolk sac. This is where the hematopoietic stem cells differentiate and begin to produce blood cells. The liver and spleen also play a role in generating blood cells, but not until later in development. The allantois functions as a structural support for the developing embryo and plays a role in waste disposal, but not in blood cell development.
