Across
  1. 3. Proteins produced by the immune system to identify and neutralize foreign objects like bacteria and viruses.
  2. 4. veins Veins located in the foot that help drain blood from the foot back to the heart.
  3. 7. The liquid component of blood that carries cells, nutrients, hormones, and waste products.
  4. 9. valve The valve that controls blood flow from the left ventricle into the aorta, the main artery supplying blood to the body.
  5. 11. vena cava A large vein that carries deoxygenated blood from the upper body to the right atrium of the heart.
  6. 15. The largest artery in the body, carrying oxygenated blood from the heart to the rest of the body.
  7. 17. veins Veins that drain deoxygenated blood from the lungs and bronchi back to the heart.
  8. 19. A red blood cell that transports oxygen and carbon dioxide in the blood.
  9. 20. cell A type of immune cell that remembers past infections to provide a quicker response upon re-exposure to the same pathogen.
  10. 21. A small vein that collects blood from capillaries and transports it to larger veins.
  11. 22. cell disease A genetic disorder that affects hemoglobin, causing red blood cells to become rigid and shaped like a sickle, leading to various health complications.
  12. 23. A white blood cell that is part of the immune system, helping the body fight infections and other diseases.
  13. 24. A fluid connective tissue that transports oxygen, nutrients, hormones, and waste products throughout the body.
  14. 26. vena cava A large vein that carries deoxygenated blood from the lower body to the right atrium of the heart.
  15. 27. One of the two upper chambers of the heart that receives blood from the body and lungs.
  16. 29. valve Also known as the mitral valve, it is located between the left atrium and left ventricle, allowing blood to flow in one direction.
Down
  1. 1. valve The valve between the left atrium and left ventricle that prevents backflow of blood.
  2. 2. artery A major artery supplying blood to the thigh and leg.
  3. 5. cycle The sequence of events in one heartbeat, including contraction and relaxation of the heart chambers.
  4. 6. rate The number of times the heart beats per minute, an important indicator of cardiovascular health.
  5. 8. The process that prevents and stops bleeding, involving blood vessel constriction, platelet plug formation, and blood coagulation.
  6. 9. A blood vessel that carries oxygenated blood away from the heart to the rest of the body.
  7. 10. block A condition where the electrical signals in the heart are delayed or blocked, affecting the heart's rhythm.
  8. 12. pressure The force exerted by circulating blood on the walls of blood vessels, measured as systolic over diastolic pressure.
  9. 13. Small cell fragments in the blood that play a crucial role in blood clotting.
  10. 14. A tiny blood vessel where the exchange of oxygen, carbon dioxide, nutrients, and waste occurs between blood and tissues.
  11. 16. The outer portion of the atrium, which helps increase the volume of blood the heart can hold.
  12. 18. A protein in red blood cells that carries oxygen from the lungs to the rest of the body and returns carbon dioxide to be exhaled.
  13. 25. skeleton A fibrous structure that provides support and electrical insulation for the heart, separating the atria from the ventricles.
  14. 28. A blood vessel that carries deoxygenated blood toward the heart.
