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