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