Across
  1. 7. valve that separates left atrium from left ventricle, has two triangular cusps
  2. 10. anterior borders of atria, muscular extensions
  3. 12. interventricular sulcus that runs on right ventricles from coronary sulcus toward apex of heart
  4. 13. cone-shaped muscles within right ventricle, anchored this strands of strong connective tissue
  5. 16. interventricular sulcus that runs on left ventricles from coronary sulcus toward apex of heart
  6. 17. receives oxygenated blood from lungs from pulmonary veins
  7. 18. internal surface of heart chambers & external surface of heart valves
  8. 20. collagen fibers that make up connective tissues of papillary muscles, attached to tricuspid & prevent prolapsing into right atrium
  9. 23. two types pulmonary & aortic, composed of three thin, half-moon-shaped, pocketlike semilunar cusps
  10. 24. formed by great vessels of heart
  11. 27. circulation that follows a path from ride side of heart & pulmonary arteries & veins, conveys blood to lungs & back to left side of heart
  12. 28. cardiac muscle, thickest of three layers
  13. 29. also known as thrombocytes, fragments of cells that help initiate clotting
  14. 31. pericardium that is outer covering of tough, dense, connective tissue
  15. 33. component of blood made of mostly water with salts, proteins, & other molecules
Down
  1. 1. layer of serous pericardium that lines inner surface of fibrous pericardium
  2. 2. consists of visceral layer of serous pericardium & areolar connective tissue
  3. 3. process that occurs in red bone marrow of epiphysis, found within spongy bone of axial skeleton
  4. 4. receives venous blood from heart & systemic circulation, superior & inferior vena cava & coronary sinus drain here
  5. 5. three time thicker than right ventricular wall
  6. 6. components of blood including erythrocytes & buffy coat made of platelets & leukocytes
  7. 8. formed by right ventricle
  8. 9. smooth area located at superior end of right ventricle
  9. 11. also known as red blood cells, carry out gas exchange with tissues, lack nucleus
  10. 14. inferior conical end of heart
  11. 15. relatively deep groove that separates atria & ventricles
  12. 19. science & study of blood
  13. 21. also known as white blood cells, five different types serving immune functions
  14. 22. also known as right atrioventricular valve separating right atrium from right ventricle
  15. 25. circulation that follows a path from left side of heart & arteries & veins, conveys blood to most body tissues & back to right side of heart
  16. 26. layer of serous pericardium that covers outer surface of heart
  17. 30. pericardium that is composed of two parietal & visceral layers
  18. 32. posterosuperior surface of heart mainly made of left atrium
