Battling Blood Cells
Whenever a germ or infection enters the body, the white blood cells snap to attention and
toward the scene of the crime. The white blood cells are continually on the lookout for
disease. When a germ does appear, the white blood cells have a variety of ways by which
attack. Some will produce protective antibodies that will overpower the germ. Others will
and devour the bacteria.
The white blood cells have a rather short life cycle, living from a few days to a few
weeks. A drop of
blood can contain anywhere from 7 000 to 25 000 white blood cells at a time. If an
fights back and persists, that number will significantly increase.
A consistently high number of white blood cells is a symptom of Leukemia, a cancer of the
Leukemia patient may have as many as 50 000 white blood cells in a single drop of blood.
