3. Vertebrate Tissue Types

4. Levels of Body Organization

9. Epithelial Tissue Covers internal and external structures Purpose
Protection
Secretion
Gas exchange
Basement membrane and connective tissue support epithelial tissue

10. Epithelial Tissue - Simple

11. Epithelial Tissue - Stratified

12. Connective Tissue Very diverse functions
Support  Cartilage, bone, dense, loose
Energy storage  Adipose
Gas exchange  Red blood cells
Immune system  White blood cells

15. Bone Structure

16. White and Red Blood Cells

17. Muscle Tissue Smooth Striated
Controls diameter of tubes (blood vessels and digestive system)
Involuntary
Striated
Skeletal – attaches to bone
Cardiac – heart muscle

18. Striated Muscle Tissue
Contain contractile unit composed of actin and myosin protein
Cells bundled together to form muscle fibers
Densely packed actin/myosin fibers gives striated appearance
Multinucleated cells – syncytial

21. Nerve Tissue Neurons – functional unit of the nervous system
Glial Cells – support cells
