Interesting Facts about White Blood(Leukocyte)

Originated from the bones

All blood cells in humans, including white blood cells are originated from hematopoietic stem cells or bone marrow in the bones. In adults, the majority of bone marrow is located in the pelvis, spine, and breastbone. However, some white blood cells can mature in your thymus gland, spleen, and lymph node. The production of blood cells can be regulated by many body organs, such as kidneys, liver, spleen, and lymph nodes. During the time of injury or infection, more white blood cells will be generated in the blood to protect your body against foreign invaders. [3]
