Across
  1. 3. when single layer can be used for diffusion, lungs & vessels
  2. 5. fibers resistant to stretch
  3. 7. secrete mucus in respiratory and digestive tracts
  4. 12. secrete chemicals outside the body
  5. 13. cushions and reduces friction where bones join and move
  6. 14. provide stretch and recoil
  7. 16. generate, send and receive electrical signals
  8. 17. act as barriers for protection, secretion and glands
  9. 19. muscle that pulls on bone
  10. 21. movement of bones, propels blood, surrounds hollow organs
  11. 22. continuously contracting cells of the heart
Down
  1. 1. when single layer can be used for secretion and absorption
  2. 2. secrete chemicals that enter the blood
  3. 4. insulation and cushioning, mostly of white fat with few mitochondria
  4. 6. stratified epithelium that undergoes stretching
  5. 7. supporting cells of the nervous tissue
  6. 8. resists against external forces, maintain organ shape
  7. 9. muscle found in hollow organs
  8. 10. rigid tissue to protect soft organs and allow for movement with muscles
  9. 11. sends information using electrical signals
  10. 15. exposed to the outside environment, respiratory, reproductive, digestive tracts
  11. 18. scaffold that keeps cells in place
  12. 19. multiple layers of cells
  13. 20. inside space of hollow organ
  14. 23. with microvilli will have increased surface area for absorption
