  7. 9. tiny sacs of lung tissue specialized for the movement of gases between air and blood
  8. 13. node small, bean-shaped masses of tissue that remove pathogens and dead cells from the lymph; concentrated in the armpits, neck, and groin; high concentration of white blood cells found in lymph nodes
