Hematopoietic system Flashcards
Medical specialty that studies blood, blood forming organs and blood related diseases
Hematology
The study of the structure of organisms
Morphology
Erythrocyte
Red blood cells
Immature red blood cells
Reticulocytes
Condition where there are more immature blood cells in the blood stream than normal
Polychromasia
Red blood cells that are of different sizes
Anisocytosis
Not having enough healthy red blood cells or hemoglobin to carry oxygen to the body tissues.
Anemia
Lower than normal number of red and white blood cells and platelets in the blood
Pancytopenia
White blood cells
Leukocyte
Condition where the body doesn’t have enough disease-fighting leukocytes in the blood
Leukopenia
Lower than normal levels of neutrophils in your blood
Neutropenia
Clumping of particles together
Agglutination
Term used to describe the appearance of cells, tissue, or cellular structures that will stain with basic dyes
Basophilic
When your body produces too many eosinophils
Eosinophilia
An increase in the number of lymphocytes in the blood
Lymphocytosis
Abnormally high number of monocytes in the blood
Monocytosis
A type of immune cell that has granules with enzymes that are released during infections, allergic reactions and asthma
Polymorphonuclear
Another term for platelet
Thrombocyte
Bodys natural process to stop bleeding and repair damaged blood vessels
Hemostasis
Blood clot
Thrombus
Type of white blood cell that engulfs and destroys foreign substances.
Phagocyte
Type of white blood cell that surrounds and kills microorganisms, removes dead cells and stimulates the action of other immune system cells
Macrophage
Medications that prevent blood clots from forming in the bloodstream
Anticoagulant
The destruction of red blood cells
Hemolysis
Clumps of red blood cells that look like stacked plates
Rouleaux
Term for bleeding, usually excessive, from a damaged blood vessel
Hemorrhage
Collection of blood that pools outside of a blood vessel usually caused by an injury or surgery
Hematoma
Blood test that measures the percentage of red blood cells in your blood, relative to the total volume of your blood
Hematocrit
Large cell that has a lobulated nucleus, is usually found in the bone marrow and is the source of blood platelets
Megakaryocyte
Increase in abnormal red blood cells of any shape that makes up 10% or more of the total population
Poikilocytosis
Lower than-normal levels of protein in the body
Hypoproteinemia
The presence of excessive amounts of lipid particles in the blood
Lipemia
Broad term for cancers of the blood cells
Leukemia
Too much bilirubin in the blood, causing yellowing of the skin and eyes
Bilirubinemia
Pertaining to the yellowing of the skin and eyes
Icteric
Cell that is the earliest precursor in the development of a normoblast or a nucleated red blood cell
Rubriblast
A basophilic normoblast that is a smaller version of a proerythroblast and lacks a nucleolus
Prorubicyte
An immature red blood cell with a nucleus and cytoplasm that stains blue, gray or purplish.
Rubricyte
Nucleated red blood cell that is in the final stage of maturation before becoming an erythrocyte
Metarubicyte
Young white blood cells develop in the bone marrow and are precursors to neutrophils.
Myelocyte
Immature white blood cells that are normally found in the bone marrow
Metamyelocyte
Protein made by the liver
Prothrombin
Protein produced in the liver that helps form blood clots to stop the bleeding and heal wounds
Fibrinogen
A red blood cell that is spherical and smaller than normal red blood cells
Spherocyte
Red blood cells with a distinctive cup or bowl shape and central slit or “mouth-like” area.
Stomacytes
Cells in the cornea that play a key role in maintaining corneal transparency and visual function
Keratocyte
Red blood cells with an abnormal membrane that has many small evenly spaced thorny projections
Echinocytes
An abnormal red blood cell with a spiked membrane also known as a spur cell
Acanthocyte
Fragmented part of a red blood cell
Schizocyte
