The White Blood Cells and The Blood Platelets

The white blood cells have two different varieties, these are under the two general groups; the phagocytes and the other one is the lymphocyte.

The white blood cells (also called leukocytes) wanders through out the blood. They do not participate in the delivery of food and they just circulate in the blood stream. They are like peace keeping forces who’s work is to protect the  body against bacteria  and other foreign- invading substances. They are true cells that have their own nuclei. Compared to the red blood cells, the white blood cells are fewer in number. There are only about 5,000 to 9,000 per cubic millimeter in  the blood.

The white blood cells have two different varieties, these are under the two general groups; the phagocytes and the other one is the lymphocyte.

The phagocytes has the capability to engulf foreign substances in the blood. The lymphocytes has the capability to produce antibodies which will attack the body enemies.

The Blood Platelets (also called thrombocytes) are the smallest blood cells. This cells only ranges from 20,000 to 500,000 millimeter in blood. The Blood Plateletes are very important because they contain a substance called Thromboplastin. Thromboplastin is a type of protien that is needed by the body for blood clothing.
