Hemopoiesis / Hematopoiesis | How Blood is Made

The video explains the process of hemopoiesis, the formation of blood cells. It covers the development of blood cells in embryos, the role of stem cells, and the differentiation into various blood components. The video details the formation of lymphoid and myeloid stem cells, leading to the creation of immune cells and other blood elements.
