They are made in the bone marrow by mitosis of cells of the hemopoietic tissue. It is a kind of connective tissue. In the embryonic condition the blood cells are made in the liver.Some leucocytes are made in the lymphatic organs such as spleen.

Red blood cells are made in the bone marrow. White blood cells (leukocytes) are made in the thymus procuded in the bone marrow but they mature in the thymus.

Blood cells i.e. the erythrocytes RBC and Lymphocytes WBC are produced in the bone marrow, RBC r produced in the red bone marrow n WBC r produced in yellow bone marrow. Bone consist of three parts - epiphysis , shaft n hypophysis, Epiphysis n hypophysis have red bone marrow n shaft constitute yellow bone marrow

The bone marrow contains Hematopoeitic tissue which is responsible for the production and control of RBC, WBC, etc in blood.
So the answer is ... Bone Marrow =)

Normally in bone marrow. In some diseases, the spleen and occasionally lymph nodes may make them.

the primary organ for blood production are your bones, specially the flat bones,i.e., ribs. although your long bones such as your thigh bones contribute a fair amount.also, another organ is the spleen,though not as much as your bones' production combined.
good luck!!!
