Across
  1. 6. The largest artery in the body, carries oxygenated blood from the left ventricle of the heart to the rest of the body.
  2. 8. The blood vessels that supply oxygen to the heart's tissues.
  3. 12. Chamber that receives deoxygenated blood from the vena cava.
  4. 13. A lower chamber of the heart where blood exits.
  5. 14. The bottom of the heart where it comes to a point.
  6. 17. A vessel that returns blood—typically deoxygenated—to the heart.
  7. 18. Chamber that receives oxygenated blood from the lungs.
  8. 20. The valve situated at the opening of the right atrium of the heart into the right ventricle. It consists of three triangular membranous flaps.
  9. 21. The transport system of the body responsible for carrying oxygen and nutrients to the body and carrying away carbon dioxide and other wastes; composed of the heart, blood vessels, and blood.
  10. 23. A major artery that branches from the arch of the aorta.
  11. 24. Muscles located in the ventricles that attach to the cusps of the tricuspid and mitral valves via the chordae tendinae.
  12. 25. The thickest chamber and is responsible for pumping oxygenated blood to tissues all over the body.
Down
  1. 1. The series of vessels that bring oxygenated blood from the heart to tissues and return deoxygenated blood from the tissues back to the heart.
  2. 2. A one-way valve by which blood leaves the heart through arteries. The valve prevents blood from returning into the right ventricle.
  3. 3. Fibrous chords that attach to the tricuspid and mitral valves.
  4. 4. A valve in the heart that guards the opening between the left atrium and the left ventricle; prevents the blood in the ventricle from returning to the atrium. Also called bicuspid valve.
  5. 5. The largest vein in the human body, it returns blood to the right atrium of the heart from body parts below the diaphragm.
  6. 7. The chamber that receives deoxygenated blood from the right atrium and pumps it to the lungs.
  7. 9. An upper chamber of the heart where blood enters.
  8. 10. A type of vessel that carries blood from the heart through the body; part of the circulatory system.
  9. 11. The ear-like extensions of the atria.
  10. 13. A body structure that temporarily closes a passage or orifice, or permits movement of fluid in only one direction.
  11. 15. Part of the circulatory system in which deoxygenated blood moves from the right ventricle of the heart to the lungs (through arteries) to become oxygenated and then returns to the left side of the heart (through veins).
  12. 16. The blood vessels that carry oxygenated blood from the lungs to the left atrium.
  13. 19. The second largest vein in the human body. It returns blood to the right atrium of the heart from the upper half of the body.
  14. 22. One of four valves in the heart, separates the left ventricle and the aorta, and functions to prevent blood from flowing back into the left ventricle.
