hemolysis
|
breakdown of red blood cells and the release of hemoglobin that occurs normally at the end of the life span of a red blood cell.
|
|
hemolytic
|
Anaemia resulting from reduced red cell survival time and haemolysis, either due to an intrinsic defect in the erythrocyte (hereditary spherocytosis or ellipsocytosis, enzyme defects, haemoglobinopathy) or an extrinsic damaging agent.
|
|
hemopoiesis
|
formation of blood cellular components.
|
|
hemolytic
|
is the breaking open of red blood cells and the release of hemoglobin into the surrounding fluid
|
|
hemorrhage
|
loss of red blood cells and the release of hemoglobbin that occurs normally at the end of the life span of a red blood cell.
|
|
hemostasis
|
termination of blood by mechanical or chemical means or by the complex coagulation process of the body, consisting of vasoconstriction, platelets aggregation, and thrombin and fibrin synthesis.
|
|
hyperlipemia/hyperlipidemia
|
excessive level of blood fats, usually caused by a lipoprotein lipase deficiency or a defect in the conversion of low-density lipoproteins to high-density lipoproteins.
|
|
