5. Life span 120 days
6. In the embryonic stage the RBC are formed in the live and spleen. But after birth, they are formed in the red bone marrow. The process of formation of RBC is known as erythropoiesis.
White blood cells (WBC)
1. They have a large characteristic nucleus
2. They are colourless as they have no pigment
3. They help in defence mechanism
4. They are about 7000/mm3 of blood
5. WBC have short life span of 5-21 days

The lifespan of white blood cells ranges from 13 to 20 days, after which time they are destroyed in the lymphatic system. When immature WBCs are first released from the bone marrow into the peripheral blood, they are called “bands” or “stabs.” Leukocytes fight infection through a process known as phagocytosis.
