Question

in are body where the blood is made ..

Answer 1

Blood isn't made, red blood cells are made. They are formed in the bone marrow of long bones.

Answer 2

In the human adult, the bone marrow produces all of the red blood cells, 60–70 percent of the white cells (i.e., the granulocytes), and all of the platelets. The lymphatic tissues, particularly the thymus, the spleen, and the lymph nodes, produce the lymphocytes (comprising 20–30 percent of the whitecells).
