Transcript of White Blood Cells

Parts Of A White Blood Cell
White blood cells have many parts in them including the nucleus, the mitochondria, the Golgi complex, the peroxisome and the endoplasmic reticulum.
Introduction
White Blood Cells

White bloods cells, sometime called leukocytes, actually account for 1 percent of your blood. However, their impact is great. White blood cells are created in your bone marrow, and then are put away and stored in your blood tissues. White blood cells are always being made by your bone marrow since they have a very short lifespan of 1 to 3 days.
Problems With White Blood Cells
When you do not have enough or too much white blood cells, they will affect your health. Too little white blood cells will make your body less immune to infection which can create a health threat. Some reasons which can cause an abnormal number of white blood cells are;
Blood Cancer
Weakened Immune System
Myeloproliferative disorder
Myelodysplastic syndrome
