Epithelial tissue
Across
- 2. inelastic fibres of great tensile strength made up of collagen protein.
- 5. the main function of epithelial tissue.
- 6. vessel, or that is exposed to the body exterior.
- 9. the epithelium with a single layer of flat cells.
- 12. the basic structural and functional unit of all organisms
- 14. the ground substance and fibers between cells in a connective tissue.
- 15. an epithelium with more layers of cells.
- 17. this epithelium seems stratified but it's not.
- 19. a cell that is as high as wide.
- 20. These short fibres cluster into a mesh-like network (reticulum = network) that covers and supports the structures bordering the connective tissue.
Down
- 1. the epithelium that lines the bladder cavity. Its apical cells change their shape as the bladder fills with urine.
- 3. the surface of a cell that faces the lumen, which is the inner cavity of an organ or
- 4. A passive process in which there is a net or greater movement of molecules or ions from a region of high concentration to a region of low concentration until equilibrium is reached.
- 6. the basal surface of epithelial cells lies on it.
- 7. it lacks blood vessels
- 8. an epithelium with a single layer of cells.
- 10. fibres composed primarily of the protein elastin (rubber like protein) that allows them to function like rubber bands.
- 11. a flat cell (it is wider than it is high).
- 13. a cell that is taller than it is wide.
- 16. a group of cells of similar structure that perform a common function.
- 18. the epithelium with a single layer of cuboidal cells.
