Across
  1. 1. Part of the heart that lies opposite of the apex and formed by left atrium.
  2. 5. venae cavae: Carries deoxygenated blood from the lower and middle body to the right atrium.
  3. 6. Swelling and irritation of the pericardium.
  4. 8. layer: Outer layer of the pericardium.
  5. 9. semilunar valves: Between the left ventricle and the aorta.
  6. 13. venae cavae: The superior of the great venous trunks that return depxygenated blood from the systemic circulation to the right atrium of the heart.
  7. 16. (AV valves): Blood flows through this valve to the ventricles.
  8. 17. interventricular: One of two grooves that seperates the ventricles of the heart.
  9. 20. (atrium): The upper two heart chambers.
  10. 22. The middle muscular layer of the heart's walls and its functions by providing a scaffolding for the heart chambers.
  11. 23. valve: Situated at the opening of the right atrium of the heart.
  12. 25. (mitral) valve: A dual flap valve in the heart that lies between the left atrium and left ventricle.
Down
  1. 2. Inner lining of the heart muscle and covers the heart valves.
  2. 3. semilunar valves: Lies beetween the right ventricle and the pulmonary artery.
  3. 4. One of two large chambers that collect and expel blood recieved from an atrium.
  4. 7. septum: The stout wall seperatinf the lower chambers of the heart.
  5. 10. sulcus (artioventricular groove):Seperates the atria from the ventricles.
  6. 11. The inner layer of the pericardium.
  7. 12. Innermost layer of the tissue the lines the chambers of the heart.
  8. 14. Conical sac of fibrous tissue that surrounds the heart.
  9. 15. The main artery of the body.
  10. 18. septum: The wall of tissue that seperates the right and left atria.
  11. 19. tendineae: Also known as hesrt strings.
  12. 21. circulation: The passage of arterial blood.
  13. 24. Tip of heart formed by the left ventricle and most inferior portion of the heart.
