20. Special characteristics
1. Special contacts: it fits close together to form tight, continuous sheets

21. Special characteristics
2. Polarity: it has two surfaces. Apical (top) is free and basal (bottom) is attached to something

22. Special characteristics
3. Supported by connective tissue

23. Special characteristics
4. Avascular but innervated: contains no blood vessels (avascular) but supplied by nerve fibers (innervated)

24. Special characteristics
5. Regenerative: rapidly replaces lost cells by mitosis

26. classification
Epithelial tissue is classified by cell shape and by how many layers of cells there are

27. Simple Epithelia has 1 layer
classification
Simple Epithelia has 1 layer

28. Stratified Epithelia has 2 or more layers
classification
Stratified Epithelia has 2 or more layers

29. classification There are 3 types of epithelial cell shapes:
Squamous: Flattened/scale-like
Cuboidal: boxlike
Columnar: Tall/rectangular/column shaped

31. glands
A gland is one or more cells that makes and secretes an aqueous (water based) fluid

32. glands Glands are classified by:
Site of product release: endocrine or exocrine
Number of cells forming the gland

33. glands Endocrine Glands Ductless glands that produce hormones
Chemical messengers carried by the blood
Secretions include amino acids, proteins, and steroids

34. glands Exocrine Glands More numerous than endocrine glands
Secrete their products onto body surfaces (skin) or into body cavities
Must use ducts
Examples include mucous, sweat, oil, and salivary glands
