Across
  1. 4. fibrous tissue connecting tricuspid leaflets with papillary muscles of the left ventricle
  2. 5. proximal or cranial extremity of the heart, broad in form as all vessels leave and return
  3. 9. semilunar valve that regulates the pumping of blood from the left ventricle to the body and coronary aa.
  4. 12. several arteries that covey oxygen rich blood to the cardiac tissue; branch immediately after the aortic valve
  5. 15. leaflet valves that regulate the movement of blood from the atria to the ventricles
  6. 16. having three leaflets, the valve that regulates the movement of oxygen rich blood from the left artrium to the left ventricle
  7. 17. depression in the intraatrial septum, the adult remnant of the foramen ovale
Down
  1. 1. external feature of the heart that marks the separation between atria and ventricles; often filled with adipose tissue and houses coronary vessels
  2. 2. thick layer of muscle separating ventricles; contains atrioventricular bundle of fibers extending from AV node to in LA species known as Purkinje fibers
  3. 3. fibrous structure that connects the pulmonary trunk with the aorta; adult remnant of the ductus arteriosus
  4. 6. semilunar valve that regulates the pumping of blood from the right ventricle to the lungs
  5. 7. caudal chambers of the heart, larger than atria, right pumps oxygen poor blood to the lungs via the pulmonic trunk, left pumps oxygen rich blood to the body via the aorta; separated from lungs and aorta by valves; lined with endocardium
  6. 8. a.k.a the mitral valve, having two leaflets, regulates the movement of oxygen poor blood from the right atrium to the right ventricle
  7. 10. enlargement of the terminal cardiac vein that returns venous blood from the heart to the right atrium
  8. 11. conical extension of myocardium of the left ventricle via the chordae tendinae prevent prolapse of the tricuspid valve
  9. 13. cranial chambers of the heart, right receives oxygen poor blood from the body and cardiac tissue and left receives oxygen rich blood from the lungs; separated from ventricles by valves; lined with endocardium
  10. 14. distal or caudal extremity of the heart, forms an apex as ventricles and intraventricular septa merge
