The study of blood and the blood-forming organs.
|
Hematology
|
|
|
Hematopoietic System Components
|
- Blood
- Bone marrow - Liver - Spleen - Kidneys |
|
|
A cell from which the various types of blood cells can form.
|
Pluripotent stem cell
|
|
|
The process through which pluripotent stem cells differentiate into various types of blood cells.

Components of Blood
|
- Plasma
- Formed elements - Red blood cells - White blood cells - Platelets |
|
|
Thick, pale yellow fluid that makes up the liquid part of the blood.
|
Plasma
|
|
|
Red blood cell.
|
Erythrocyte
|
|
|
Oxygen-bearing molecule in the red blood cells. It is made up of iron-rich red pigment called heme and a protein called globin.
|
Hemoglobin
|
|
|
Phenomenon in which a decrease in PCO2 acidity causes an increase in the quantity of oxygen that binds with the hemoglobin and, conversely, an increase in PCO2 acidity causes the hemoglobin to give up a greater quantity of oxygen.
|
Bohr effect
|
|
|
Chemical in the red blood cells that affects hemoglobin's affinity for oxygen.
|
2,3-diphosphoglycerate (2,3-DPG)
|
|
|
The process of producing red blood cells.
|
Erythropoiesis
|
|
|
Destruction of red blood cells.
|
Hemolysis
|
|
|
The trapping of red blood cells by an organ such as the spleen.
|
Sequestration
|
|
|
The packed cell volume of red blood cells per unit of blood.
|
Hematocrit
|
|
|
White blood cells.
|
Leukocyte
|
|
|
The movement of white blood cells in response to chemical signals.
|
Chemotaxis
|
|
|
Process in which white blood cells engulf and destroy an invader.
|
Phagocytosis
|
|
|
The process through which stem cells differentiate into the white blood cells' immature forms.
|
Leukopoiesis
|
|
|
White Blood Cell Blasts
|
- Myeloblasts
- Monoblasts - Lymphoblasts |
|
|
White Blood Cell Categories
|

- Monocytes - Lymphocytes |
|
|
Granulocyte Classifications

- Eosinophils - Neutrophils |
|
|
A larvacidal peptide.
|
Major basic protein (MBP)
|
|
|
A reduced number of neutrophils.
|
Neutropenia
|
|
|
Condition in which the body makes antibodies against its own tissues.
|
Autoimmune disease
|
|
|
A nonspecific defense mechanism that wards off damage from microorganisms or trauma.
|
Inflammatory process
|
|
|
Blood platelet.
|
Thrombocyte
|
|
|
The combined three mechanisms that work to prevent or control blood loss.
|
Hemostasis
|
|
|
The process through which plasmin dismantles a blood clot.
|
Fibrinolysis
|
|
|
Clot formation, which is extremely dangerous when it occurs in coronary arteries or cerebral vasculature.
|
Thrombosis
|
|
|
Protein of the surface of a donor's red blood cells that the patient's body recognizes as "not self."
|
Antigen
|
|
|

Polycythemia
|
|
|
An inadequate number of red blood cells or inadequate hemoglobin within the red blood cells.
|
Anemia
|
|
|
Diseases of the Red Blood Cells
|

|
|
An inherited disorder of red blood cell production, so named because the red blood cells become sickle shaped when oxygen levels are low.
