The Cardiovascular System

  1. Anemia
    A general term for a group of disorders that affect the ability of the red blood cells to carry oxygen to the cells and tissues of the body
  2. Angina pectoris
    The classic chest pain that is felt as a result of the heart muscle being deprived of oxygen
  3. Arteries
    Vessels that carry blood away from the heart
  4. Arterioles
    The smallest arteries
  5. Arteriosclerosis
    "Hardening of the arteries;" occurs when atherosclerosis plaques interfere with the elasticity of the arterial walls, making them brittle and prone to breaking
  6. Atherosclerosis
    Blocking of the arteries, caused by the build-up of fatty deposits called plaques on the inside of the vessel wall
  7. Atria
    The upper chambers of the heart
  8. Capillary bed
    The network of tiny vessels in the tissues where the oxygen and nutrients in the blood pass into the tissues, and carbon dioxide and other waste materials from the tissue pass into the blood
  9. Cardiac cycle
    The pumping action of the heart in an organized pattern (all of the evens associated with one heartbeat)
  10. Circulation
    The continuous movement of the blood through the blood vessels; powered by the pumping action of the heart
  11. Coagulation
    Clotting of the blood
  12. Coronary artery disease
    A disorder that occurs when the arteries that supply the heart (the coronary arteries) narrow as a result of atherosclerosis, preventing adequate blood flow to the heart muscle
  13. Diastole
    The resting phase of the cardiac cycle; during which the myocardium relaxes, allowing the chambers to fill with blood
  14. Embolus
    A blood clot in a vessel that breaks off and moves from one place to another
  15. Endocardium
    The smooth inner lining of the heart wall
  16. Epicardium
    The smooth outermost layer of the heart wall
  17. Erythocytes
    Red blood cells; responsible for carrying oxygen to all of the tissues of the body
  18. Heart failure
    A condition that occurs when the heart is unable to pump enough blood to meet the body's needs
  19. Hemoglobin
    A protein found in red blood cells that combine with oxygen to carry it to the tissues of the body
  20. Hemostasis
    The process of stopping blood loss from the circulatory system
  21. Ischemia
    The state that occurs when the flow of oxygen-rich blood to the tissue is interrupted, leading to an oxygen deficiency in the tissues
  22. Leukemia
    A general term for a group of disorders characterized by the excessive production of white blood cells that are abnormal in structure
  23. Leukocyte
    White blood cell
  24. Lymph
    Fluid in the lymph vessels (vessels that return the fluid that leaks into the tissues to the bloodstream)
  25. Lymph node
    Masses of lymphatic tissue that "clean" the lymph by removing bacteria and other large particles before returning the fluid to the bloodstream
  26. Myocardial infarction
    A "heart attack;" occurs when one or more coronary arteries becomes completely blocked, preventing blood from reaching the parts of the heart that are fed by the affected arteries
  27. Myocardium
    The thick, muscular middle layer of the heart wall; responsible for the pumping action of the heart
  28. Pericardium
    A double-layered protective sac that surrounds the heart
  29. Peripheral vascular disease
    A disorder characterized by pain and cramping in the legs, caused by atherosclerosis of the arteries that supply the legs
  30. Phlebitis
    Inflammation of a vein
  31. Plaque
    A fatty deposit that builds up on the inside of the artery wall, blocking blood flow to the tissues and making the artery wall brittle and prone to breaking
  32. Plasma
    The liquid part of the blood
  33. Pumonary circulation
    The pattern of circulation that takes blood from the heart to the lungs to pick up oxygen and release carbon dioxide
  34. Pulmoary embolism
    A potentially fatal condition caused by the blocking of the pulmonary artery by an embolus (a blood clot in a vessel that breaks off and moves from one place to another)
  35. Systemic circulation
    The pattern of circulation that takes blood from the lungs to the rest of the body to release oxygen and pick up carbon dioxide
  36. Systole
    The active phase of the cardiac cycle, during which the myocardium contracts, sending blood out of the heart
  37. Thrombi
    Blood clots that form in the small blood vessels, blocking the flow of blood and depriving the tissues of oxygen and nutrients
  38. Thrombocytes
    Pinched-off pieces of larger cells that are found in the red bone marrow and are responsible for clotting of the blood; also called platelets
  39. Thrombophlebitis
    A condition characterized by inflammation and pain in the legs, caused by a thrombus in one of the veins of the legs
  40. Varicose veins
    A condition that results from pooling of blood in the veins just underneath the skin, causing them to become swollen and "knotty" in appearance
  41. Veins
    Vessels that return blood to the heart
  42. Venous (stasis) ulcers
    Open sores that occur on the lower legs, usually in the ankle area, as a result of pooling of blood in the veins
  43. Venous thrombosis (Deep Vein Thrombosis, DVT)
    The formation of blood clots (thrombi) in the veins as a result of pooling of the blood
  44. Ventricles
    The lower chambers of the heart
  45. Venules
    The smallest veins
