Final answer:
The sequential order of organs or tissues responsible for producing red blood cells in babies, leading up to the involvement of the bone marrow, begins with the yolk sac in the embryo, followed by the spleen, lymph nodes, and liver, and finally the bone marrow.
Step-by-step explanation:
The sequential order of the organs or tissues responsible for producing red blood cells in babies, leading up to the involvement of the bone marrow in this process, begins with the yolk sac in the embryo. As development progresses, the function of blood cell production is taken over by the spleen, lymph nodes, and liver. Finally, the bone marrow becomes the primary site for hematopoiesis, where most of the red blood cells, white blood cells, and platelets are produced.
