Coagulation: fibrin clot Anticoagulants: heparin, warfarin (Coumadin) What is blood clotting or coagulation? The final result (usually taking less than 15 minutes) is the formation of a fibrin clot from the plasma protein fibrinogen. Why are platelets important in the beginning of the process following injury to tissues or blood vessels?

increase in numbers of LARGE cells

Disease of Bone Marrow Cells
multiple myeloma: Malignant neoplasm of bone marrow. Malignant cells destroy bone tissue and cause overproduction of immunoglobulins. The malignant cells destroy bone tissue and cause the overproduction of immunoglobulins, including Bence Jones protein. What is Bence Jones protein? (An immunoglobulin fragment found in urine) How is this treated?
derived from bone marrow
myeloid (myel = bone marrow, -oid = derived/resembling)
Deficiency in numbers of white blood cells (in this case, a deficiency of neutrophils)
neutropenia
relieving, but not curing
pallative
deficiency of ALL blood cells
pancytopenia (pan- = all, cyt/o = cell, -penia = deficiency)
-lytic
pertaining to destruction
