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.
Hematopoisis
The hormone responsible for red blood cell production.
Erythropoietin
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
- Granulocytes
- Monocytes
- Lymphocytes
Granulocyte Classifications
- Basophils
- 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
Blood Types
- A
- B
- AB
- O
An excess of red blood cells.
Polycythemia
An inadequate number of red blood cells or inadequate hemoglobin within the red blood cells.
Anemia
Diseases of the Red Blood Cells
- Anemia
- Sickle cell disease
- Polycythemia
An inherited disorder of red blood cell production, so named because the red blood cells become sickle shaped when oxygen levels are low.
Sickle cell anemia
Sickle Cell Crises
- Vasoocclusive
- Hematological
- Infectious
Too few white blood cells.
Leukopenia
Too many white blood cells.
Leukocytosis
Diseases of the White Blood Cells
- Leukopenia/neutropenia
- Leukocytosis
- Leukemia
- Lymphoma
A cancer of the heatopoietic cells.
Leukemia
A cancer of the lymphatic system.
Lymphoma
Platelet Abnormalities
- Thrombocytosis
- Thrombocytopenia
- Hemophilia
- von Williebrand's disease
An abnormal increase in the number of platelets.
Thrombocytosis
An abnormal decrease in the number of platelets.
Thrombocytopenia
A cancer of the heatopoietic cells.
Leukemia
A cancer of the lymphatic system.
Lymphoma
Platelet Abnormalities
- Thrombocytosis
- Thrombocytopenia
- Hemophilia
- von Williebrand's disease
An abnormal increase in the number of platelets.
Thrombocytosis
An abnormal decrease in the number of platelets.
Thrombocytopenia
