is a type of cancer that affects the body's ability to produce
normal white blood cells. In Leukemia, the body makes too many
abnormal white blood cells, causing-
Leukemic cells lack the infection-fighting
ability of normal white blood cells.
Production of red blood cells drops as leukemic cells flood
Clotting ability decreases as number of platelets (tiny disk-shaped
cells needed for clotting) drops.
Production in a healthy human:
are three types of blood cells that are produced in the bone
marrow of a healthy human being: red blood cells (RBCs), white
blood cells (WBCs) and platelets. Their ability to carry out
their specified functions is instrumental to staying healthy
and preventing infections.
- red blood cells carry oxygen and carbon dioxide
- specialized white blood cells protect the body from foreign
- neutrophils kills most regular bacteria. They accumulate
as pus or infected wound on skin.
- monocytes kill bacterial infections such as tuberculosis.
- lymphocytes are responsible for killing viruses and
the overall management of immune system. They recognize
foreign materials and increase the body's resistance to
- platelet cells help clot the wound in case of bleeding.
The risk of bleeding without clotting increases if the platelet
count is less than 10,000-20,000.
