Down
  1. 1. WBC that counteracts foreign substances and disease
  2. 2. tube from larynx to the bronchial tubes conveying air to and from the lungs
  3. 4. surface covered in moist epithelial cells that allow oxygen and carbon dioxide to exchange
  4. 6. insolunle protein that impedes flow of blood to clot it
  5. 7. pacemaker of heart in right atrium
