Show Answers:

  1. Aortic Semilunar Valve
    Heart valve that prevents blood from returning to the left ventricle.
  2. Arterioles
    Small arteries that carry blood to the capillaries.
  3. Arteriosclerosis
    Hardening of the arteries.
  4. Artery
    Blood vessel that transports blood high in oxygen from the heart with the exception of the pulmonary artery and the umbilical artery.
  5. Atria/Atrium
    Upper chamber of heart. Right or Left. Contains both oxygenated and deoxygenated blood.
  6. Atrioventricular Node
    AV Node. Specialized group of cardiac cells located in the lower left portion of the right atrium.
  7. Bacterial Endocarditis
    Inflammation of the endocardium and heart valves caused by an infection by a microbe.
  8. Bundle of His
    Atrioventricular bundle.
  9. Capillary
    smallest blood vessel that moves oxygen into and removes waste products from body tissues.
  10. Cardiac Catheterization
    Type of angiography. Procedure that visualizes heart activity and measures pressure within the heart chambers using catheterization (threading) of the heart.
  11. Carotid Pulse
    Located on each side of the neck. Used to check adult pulse for CPR.
  12. Coarctation
  13. Coarctation of the Aorta
    Congenital cardiac anomaly characterized by a localized narrowing of the aorta causing a decrease in blood flow.
  14. Diastole
    Relaxation of the heart.
  15. Dorsalis Pedis Artery
    Located in the upper surface of the foot. Used to check blood supply to the lower extremities. Supplies blood to muscles of foot and toes.
  16. Electrical Impulses
    SA Node, AV Node, Bundle of His, Right and Left Bundle Branches, and Purkinje Fibers.
  17. Epicardium
    Outermost layer of the heart wall.
  18. Heart
    Located on the left side of the chest and is protected by the sternum and thoracic vertebrae.
  19. Holter Monitor
    Portable electocardiograph that is worn for 24 hrs to record a person's heart activity during daily activities.
  20. Ischemia
    Deficiency of a blood supply to tissue because of obstruction. Occurs when teh heart muscle is deprived of oxygen.
  21. Mitral Valve
    Bicuspid Valve. Heart valve located between the atrium and the left ventricle.
  22. Murmurs
    Abnormal heart sounds caused by malfunctioning valves.
  23. Myocardial Infarction
    MI or Heart Attack. Death of mycardial tissue caused by lack of oxygen.
  24. Pulmonary Artery
    Does not carry oxygenated blood.
  25. Pulmonary Circulation
    Movement of blood from the heart to the lungs and back.
  26. Pulmonary Semilunar Valve.
    Valve that prevents backflow into the right ventricle.
  27. Pulse Sites
    brachial artery, carotid artery, dorsalis pedis artery, femoral artery, popliteal artery, radial artery, and temporal artery.
  28. Purkinje Fibers
    fibers that form the right and left branches of the bundle of His and extend along outer walls of the ventricles, causing them to contract.
  29. Right Atrium
    Deoxygenated blood from the body returns to the heart and enters here.
  30. Sinoatrial Node
    SA Node. Specialized group of cardiac cells that functions as the natural pacemaker of the heart, located in the upper portion of the right atrium and responsible for the electrical impulse that fires the heart.
  31. Systemic Circulation
    Movement of blood from the heart throughout the entire body and back.
  32. Tricuspid Valve
    Heart valve located between the right atrium and the right ventricle.
  33. Umbillical Artery
    Does not carry oxygenated blood.
  34. Vein
    Blood vessel with valves that carries blood low in oxygen toward the heart.
  35. Venule
    Blood vessel that carries blood from the capillary to the vein.
