3. A 2.
Does A or B represent tight junctions? B A

4. 5. What is the difference between a secretion and an excretion?
Secretion is a product the cell makes that is used elsewhere. An excretion is a waste product that the cell must get rid of.

Columnar

17. 7. What process is shown by the red arrows?
Absorption

18. 6. What process is shown by the green arrows?
Secretion

19. 19. What is the name of the cell feature is shown here?
Microvilli

20. Increases surface area within the same volume.
20. What is the function of the cell feature is shown here?
Increases surface area within the same volume.

21. 21. The cell shape actually found in pseudostratified tissue is __________ although it is hard to tell because it is all smashed together.
Columnar

22. 27. Give the specific name of this epithelial tissue.
Stratified cuboidal

23. 25. What type of exocrine gland is illustrated here?
Holocrine

24. 10. All epithelia tissue has great mitotic capability
10. All epithelia tissue has great mitotic capability. What does this mean?
It undergoes cell division quite often, and is always replacing worn and sloughed off cells.

25. 24. What type of glands retain ducts to body surfaces?
Exocrine

26. 23. What is the name of this epithelia tissue?
Pseudostratified

27. The cilia beat back and forth to move items past the cells.
18. What is the specific function of this cell feature in our bodies?
The cilia beat back and forth to move items past the cells.

28. Keratinized stratified squamous
28. Give the specific name of this epithelial tissue.
Keratinized stratified squamous

29. 29. Give the specific name of this epithelial tissue.
Simple squamous

30. EXOCRINE
31. Does this represent an exocrine gland or an endocrine gland?

31. 30. Name these specific cells (re arrows)
Goblet cells

32. 33. What is the rule when naming a tissue as shown here?
Use the shape of the most cells having the apical surface pointing toward the lumen. Here is would be cuboidal.

33. 36. What do goblet cells secrete?
mucus

34. 26. What type of exocrine gland is illustrated here?
Apocrine

35. 35. What is so unique about transitional epithelium tissue?
The ability to stretch from a multi-layered tissue to a tissue with very few layers.

36. Non-keratinized Stratified Squamous Epithelia

37. 34. Name this part of the tissue outlined in yellow.
Keratin
