The process whose specific outcome is the progression of the myeloid and lymphoid derived organ/tissue systems of the blood and other parts of the body over time, from formation to the mature structure. The site of hemopoiesis is variable during development, but occurs primarily in bone marrow or kidney in many adult vertebrates. Erythrocyte differentiation which occurs as part of the process of primitive hemopoiesis. Development, taking place during the embryonic phase, of a tissue or tissues that work together to perform a specific function or functions. Development pertains to the process whose specific outcome is the progression of a structure over time, from its formation to the mature structure. Organs are commonly observed as visibly distinct structures, but may also exist as loosely associated clusters of cells that work together to perform a specific function or functions. A first transient wave of blood cell production that, in vertebrates, gives rise to erythrocytes (red blood cells) and myeloid cells. The process whereby a relatively unspecialized cell acquires the characteristics of a mature hemangioblast. Hemangioblasts are the proposed common precursor of blood and endothelial lineages. The stages of blood cell formation that take place within the embryo.
