Across
  1. 5. largest artery
  2. 8. muscles fingerlike projections of ventricles; pull on chordae tendonae
  3. 10. "SA" node controls contraction of atria; "pacemaker"
  4. 13. "AV" node controls contraction of ventricles
  5. 14. fibers conductive fibers; AV bundle to ventricular walls
  6. 16. valve separates heart from artieries
  7. 17. wall between heart chambers
  8. 20. small blood vessels; between arteries and veins; where gas exchange occurs
  9. 22. tendonae "hearstrings"; pulled by papillary muscles; attach to cusps
  10. 23. carry blood to heart
  11. 25. iliac vein brings blood from legs
  12. 26. small veins
  13. 27. pressure BP after ventricular contraction; artieries
  14. 29. atrium left upper chamber of heart
Down
  1. 1. circuit pulmonary artery, pulmonary arterioles, pulmonary capillaries, pulmonary venules, pulmonary veins
  2. 2. vena cava (vein) largest vein to heart from below
  3. 3. pressure BP after ventricular relaxation; arteries
  4. 4. vein under clavicle; returns blood from the arms to the heart
  5. 6. small arteries
  6. 7. valve valve between left atrium/ventricle
  7. 9. valve valve between right atrium/ventricle
  8. 11. carry blood away from heart
  9. 12. artery supplies heart with blood
  10. 15. vein return blood from head
  11. 18. heart relaxation
  12. 19. atrium right upper chamber of heart
  13. 21. vena cava (vein) largest vein to heart from above
  14. 24. arteries brachiocephalic, bronchial, pericardial, esophageal, mediastinal, intercostal, celiac, phrenic, mesenteric, suprarenal, renal, gonadal, inferior mesenteric, lumbar, middle sacral, common iliac, superior thyroid, lingual, facial, occipital, posterior, maxillary, superficial, opthamalic, anterior choroid, anterior cerebral
