| MACROPHAGE | phagocytic leukocytes found wandering outside of the bloodstream, in the tissues of the body |
| ANTICOAGULANT | any chemical agent that prevents clotting of blood |
| HEMOLYSIS | the process of destroying blood |
| HEMORRHAGE | blood escaping / bleeding |
| HEMATOMA | a localized accumulation of blood between tissues / tissue layers, due to a break in a blood vessel |
| HEMATOCRIT | to separate blood |
| MEGAKAROCYTE | a cell found in the bone marrow that contains a very large nucleus and from which platelets are formed |
