Across
  1. 4. Remove oxygen from
  2. 5. Ensures one-way blood flow within the heart into the left ventricle
  3. 6. Blood vessels that return deoxygenated blood from the body back into the heart
  4. 9. Tiny blood vessels that connects veins and arteries so that they can exchange oxygen, nutrients, and waste products between the blood and body's cells
  5. 11. Controls the flow of blood between the right atrium and the right ventricle
  6. 12. Receives oxygenated blood from the lungs and then pumps it into the left ventricle
  7. 15. Pumps deoxygenated blood from the body into the lungs
  8. 17. Controls the flow of blood from the hearts's left ventricle into the aorta
  9. 18. Transports deoxygenated blood from the right side of the heart to the lungs
  10. 19. Separates the heart's left and right side making sure that oxygenated and deoxygenated blood don't mix
  11. 20. Pumps oxygenated blood from the left atrium to the aorta
Down
  1. 1. Carries oxygen, nutrients, hormones, and wastes products throughout the body
  2. 2. Regulates blood flow from the heart's right ventricle into the pulmonary artery, which leads to the lungs
  3. 3. A muscular organ that acts as a pump, making sure the body has blood
  4. 7. The body's network of organs and tissues responsible for transporting blood, oxygen, nutrients, and hormones throughout the body
  5. 8. Receives deoxygenated blood from the body and the pumps it into the right ventricle
  6. 10. Collects deoxygenated blood from the upper body and returns it to the right atrium
  7. 13. Carrying oxygenated blood from the lungs back to the heart
  8. 14. Large blood vessels the carry oxygenated blood away from the heart to the body's tissues
  9. 16. Carries oxygen-rich blood from the heart to the rest of the body
