Across
  1. 2. Decrease in lumen size
  2. 3. Microscopic vessels that are in organs and tissues
  3. 6. Valve between right ventricle and pulmonary trunk.
  4. 8. Valves controlling blood leaving the heart.
  5. 10. drain the heart of the oxygen-poor blood in the heart.
  6. 12. Returns blood from the upper body to the right atrium.
  7. 15. Carry blood away from the heart
  8. 18. Flap that increases the volume of the atrium.
  9. 19. AV valve on the left side (2 flaps).
  10. 24. Lower chambers that pump blood out of the heart.
  11. 25. valves Structures that keep blood flowing in one direction.
  12. 26. Carry blood back towards the heart
  13. 27. Middle layer of the vessels / smooth muscles elastic connective tissue
  14. 30. Upper chambers of the heart that receive blood.
  15. 33. when blood flows through pulmonary arteries and Aorta, the semilunar valves shut and create a sound referred to as a dub
  16. 34. Open and close to regulate capillary blood flow
  17. 35. Moves blood between the heart and lungs to pick up oxygen and remove carbon dioxide.
  18. 36. Returns blood from the lower body to the right atrium.
  19. 37. core of the arteries
  20. 38. Smaller vessels divided from arteries
  21. 39. Blood flow from heart → body → back to heart.
  22. 40. Smaller veins that emerge from capillaries
  23. 43. A serious condition where the body doesn’t get enough oxygen and nutrients due to poor circulation.
  24. 44. Affects blood pressure based on emotions like stress, anger, or depression.
  25. 45. Relaxing of the heart muscle
  26. 46. Special receptors near the aorta that monitor blood oxygen and carbon dioxide levels.
Down
  1. 1. Muscles that contract to prevent valve inversion.
  2. 3. Sense oxygen, carbon dioxide, and pH levels in the blood and help regulate breathing and circulation.
  3. 4. Carry oxygen-rich blood from lungs to the left atrium.
  4. 5. Valves between atria and ventricles.
  5. 7. the arteries that supply the heart with the oxygen-rich blood that it needs to function
  6. 9. The sound your heart makes when your atrioventricular valve shuts
  7. 11. Contracting of the heart
  8. 13. Valve between left ventricle and aorta.
  9. 14. The three vessel (Except capillaries) layers of cells
  10. 16. Controls water levels in the blood and can cause blood vessels to tighten.
  11. 17. Detect changes in blood pressure and send signals to adjust heart rate and blood flow.
  12. 20. is where the coronary sinus drains the blood into. the oxygen deprived blood will flow into the right chamber of the heart
  13. 21. The specific wall dividing the heart chambers internally.
  14. 22. Outer layer of blood vessel
  15. 23. Increase in lumen size
  16. 27. AV valve on the right side (3 flaps).
  17. 28. Condition where the mitral valve does not close properly.
  18. 29. A type of shock caused by losing a lot of blood or fluids.
  19. 31. Controls blood vessel size and helps maintain blood pressure by sending nerve signals.
  20. 32. String-like cords that attach valves to papillary muscles.
  21. 41. Inner lining of the lumen
  22. 42. Wall that separates the left and right sides of the heart.
