4 Kinds: Epithelial, Connective, Muscle, Nervous
Basement Membrane: Underside of tissue, nonliving layer

4. Tissue
Epithelial Tissue: Tissue that covers body surface, organs, and glands.
Used for protection, secretion, absorption, and excretion

8. Simple Cuboidal Epithelium
Cube-shaped cells, tightly packed
Ovaries, kidneys, salivary glands, liver

9. Simple Columnar Epithelium

10. Simple Columnar Epithelium
Elongated, single layer cells.
Can contain Cilia: for movement of materials
Female reproductive tubes, small and large intestines

11. Pseudostratified Columnar Epithelium

12. Pseudostratified Columnar Epithelium
Single, elongated layer, but appear stratified because nuclei are located at different levels
Line passages of respiratory system, trap dust and microorganisms

13. Stratified Squamous Epithelium

14. Stratified Squamous Epithelium
Many layers, thick tissue. New cells push older ones further out
Outer layer of skin, esophagus, vagina, anal canal

15. Stratified Cuboidal Epithelium

19. Transitional Epithelium

20. Transitional Epithelium
Specialized to contract and expand based upon tension
Bladder and uterus

21. Glandular Epithelium
Cells that produce and secrete substances into ducts and body fluids
Exocrine Glands: secrete their product on open surfaces (Skin, digestive tract)
Endocrine Glands: Secrete into tissue fluid and blood
