Across
- 2. ________epithelium- Multiple layers of cells
- 3. _________epithelium- Side view: square with large round nucleus in center, Top view: hexagonal boxes
- 5. “spot welds” between cells
- 7. ________epithelium- single layer of cells covering basement membrane
- 8. __________junctions- Prevents passage of water and solutes between cells. Keeps stomach acids, and waste from leaking to surrounding cells.
- 10. _____________secretions (called hormones) released into surrounding tissue fluid and blood
- 13. __________surface is exposed to an internal or external environment
- 14. __________junctions- tubular passageways between cells. This allows small molecules and ions to pass through. Found in cardiac and smooth muscle tissue where coronation is important
