this procedure stearted from stem cell.and then differentiate in to two way.one way is for the red blood cell and another one is white blood cell.and third one is platelet. stem cell differ into bone marrow and two types of bone marrow available in our body one is yellow and second one is red.

Hematopoietic stem cells in the bone marrow give rise to the three classes of blood cell that are found in the circulation: white blood cells (leukocytes), red blood cells (erythrocytes), and platelets (thrombocytes).

Blood is an extremely complex fluid composed of both formed elements (red cells, white cells, platelets), and plasma. All of these cells are different in structure and function but they begin in the bone marrow from a common progenitor cell called a stem cell. The red cells carry oxygen from the lungs to body tissues by attaching the oxygen to hemoglobin, a pigmented substance in red cells that contains iron. When the amount of hemoglobin or the total amount of red cells falls below a certain number, the possibility of anemia exists. There are many types of anemia, some are caused by vitamin or mineral deficiencies or an inability to absorb certain nutrients; destruction of red blood cells, inherited abnormalities in the blood, or the failure of the bone marrow to manufacture sufficient numbers of red blood cells. Cancers like leukemia (cancer of the blood), or lymphoma (cancer of the lymph system), and chronic diseases like lupus, hepatitis or polyarthritis, ulcerative colitis and hypothyroid disease can all be underlying causes of anemia. Reactions to vaccines, drugs and toxins can also cause anemia.
Red blood cells have a normal life span of up to 120 days. The bone marrow continually produces red cells throughout life but when these cells are destroyed prematurely, it is called hemolytic anemia. In this disease, the red cells break down faster than the bone marrow can replace them. Remember, red cells carry oxygen and nutrients to every cell in the body, while removing waste. When these cells break down faster than they can be replaced, the body can die without treatment.
The last formed element making up the blood and manufactured from stem cells in the bone marrow are white blood cells which function to protect the body from foreign organisms—virus, bacteria, any disease causing agents. Because of this function, the body will produce more white cells than normal in response to infections. These changes show up as elevated white cells on a blood test. White blood cell numbers can increase in response to inflammation, allergies, and infection or even stress. In cancers like leukemia, either the numbers of white blood cells are increased or their appearance is abnormal, or both.
A decrease in white blood cells may indicate an overwhelming infection like Parvo virus which results in a steep drop of white blood cells characteristic of this disease; with bone marrow disorders, or a decrease can be a reaction to drugs or a toxic chemical.
Neutrophils, monocytes, eosinophils, basophils and lymphocytes are white blood cells, each with its own function:
Neutrophils are elevated in acute bacterial infections or during times of extreme stress.
Lymphocytes are reduced during the initial stages of infections, or after steroid use.
Monocytes are generally constant except when leukemia is present.
Eosinophils increase in parasitic infections and during allergies reactions but will decrease under prolonged stress.
Little is understood about Basophils and their functions.

bloods made up of - plasma,rbc&wbc
rbc's produced in marrow of long bones. in embryo it is produced in liver and spleen
wbc is produced in bone marrow &lymph nodes
