The flashcards below were created by user Jtrosmarin on FreezingBlue Flashcards.

  1. Erythrocyte
    Red blood cell that transports oxygen and carbon dioxide within the bloodstream.
  2. Leukocyte
    A white blood cell; typically functions in immunity, such as phagocytosis or antibody production.
  3. Platelet
    A cell fragment that plays an important part in forming blood clots.
  4. Plasma
    Colorless watery fluid of blood and lymph containing no cells and in which erythrocytes and leukocytes and platelets are suspended.
  5. Hematocrit
    The percentage of erythrocytes to total blood volume.
  6. Hemoglobin
    Iron-containing protein in red blood cells that transports oxygen from the lungs to the tissues of the body.
  7. Hematopoiesis
    Formation and development of red and white blood cells from stem cells. Occur in bone marrow.
  8. Hemocytoblast
    Stem cell that gives rise to all blood cells, resides in the red bone marrow.
  9. EPO
    Glycoprotein hormone produced by kidney. Stimulates development/ production of RBCs.
  10. Anemia
    Blood having abnormally low oxygen carrying capacity, due to a reduced number or size of the red blood cells.
  11. Polycythemia
    A disorder characterized by an abnormal increase in the number of red blood cells in the blood.
  12. Intrinsic Factor
    A substance produced by the mucosa of the stomach and intestines that is essential for the absorption of vitamin B12.
  13. Granulocytes
    A group of leukocytes containing granules in their cytoplasm; neutrophils, eosinophils, basophils.
  14. Agranulocytes
    A group of leukocytes without granules in their nuclei; lymphocytes, monocytes.
  15. Neutrophils
    The most abundant type of white blood cell. They are phagocytic and tend to self-destruct as they destroy foreign invaders, limiting their life span to a few days.
  16. Eosinophils
    White blood cell that are responsible for combating infection by parasites in vertebrates.
  17. Basophils
    A type of WBC that promotes inflammation and participates in allergic responses.
  18. Lymphocytes
    The two types of white blood cells that are part of the body's immune system.
  19. Monocytes
    An agranular leukocyte that is able to migrate into tissues and transform into a macrophage.
  20. Leukemia
    Cancer characterized by an increase in abnormal white blood cells.
  21. Hemostasis
    Stoppage of blood flow.
  22. Thrombus
    A blood clot formed within a blood vessel and remaining attached to its place of origin.
  23. Embolus
    A clot that breaks lose and travels through the bloodstream.
  24. Thromboembolytic disorders
    Undesirable clot formation.
  25. Agglutinogens
    Antigens formed on the surface of red blood cells, whose presence and structure are genetically determined.
  26. Agglutinins
    Specific antibodies formed in the blood.
  27. Atrium
    Upper chamber of the heart that receives and holds blood that is about to enter the ventricle.
  28. Ventricle
    A chamber of the heart that receives blood from an atrium and pumps it to the arteries.
  29. Aorta
    The largest artery in the body; the large trunk artery that carries blood from the left ventricle of the heart to branch arteries.
  30. Vena Cava
    Largest vein in the body; either of two large veins that return oxygen-depleted blood to the right atrium of the heart.
  31. Pulmonary Artery
    One of two arteries (branches of the pulmonary trunk) that carry venous blood from the heart to the lungs.
  32. Pulmonary Vein
    Any of four veins that carry arterial blood from the lungs to the left atrium of the heart.
  33. Hypertension
    Abnormally high blood pressure.
  34. HbF
    Fetal Hemoglobin.
  35. Erythropoeisis
    • Process of making new red blood cells.
    • Aplastic anemia
    • Severe form of anemia that develops as a consquences of loss of functioning red bone marrow.
  36. Pernicious anemia
    Progressive anemia that results from a lack of intrinsic factor essential for the absorption of vitamin B12.
  37. Sickle-Cell anemia
    Low O2 from irregular shaped RBC , joint pain, thrombosis, anemia fever.
  38. Arteries
    Blood vessels that carry blood away from the heart.
  39. Veins
    Blood vessels that carry blood back to the heart.
  40. Blood Alkalinity
    pH between 7.35 to 7.45.
  41. Erythroblastosis fetalis
    Disorder that results from the incompatibility of a fetus with an Rh-positive blood factor and a mother who is Rh negative, causing red blood cell destruction in the fetus; this condition necessitates a blood transfusion to save the fetus.
  42. Capillaries
    The smallest blood vessels which connect the smallest arteries with the smallest veins.
  43. 120/80
    Normal blood pressure for a healthy adult.
  44. SA node
    A specialized bit of heart tissue that controls the heartbeat.
  45. AV node
    Picks up electrical impulse from the SA node and causes ventricles to contract, causing blood to move into arteries
  46. Bundle of His
    A bundle of modified heart muscle that transmits the cardiac impulse from the atrioventricular node to the ventricles causing them to contract.
  47. Chordae tendineae
    "Heart strings" are tiny white collagenic cords that anchor the cusps to the ventricular walls. They originate from the papillary muscles.
  48. Diastolic
    The blood pressure during that part of the heartbeat when the hearts venticles are relaxing.
  49. Systolic
    The blood pressure during that part of the heartbeat when the heart's ventricles are contracted and the blood is being pushed out into the arteries.
