11. Vertebrates
-Have a backbone made up of individual bones called vertebrae
-More complex animals
-Have an endoskeleton
-Phylum Chordata  Subphylum Vertebrata
-6 Common classes from simplest to most complex

12. 1. Cartilage Fish – Sharks & Stingrays

REGULATION: Excretory & Nervous Systems
NUTRIENT ABSORPTION: Respiration, Digestion, & Circulatory Systems
DEFENSE: Immune, Integumentary, Lymphatic, Skeletal, & Muscular Systems
Reproduction: Reproductive & Endocrine Systems

19. Dissection Terms Dorsal – back or upper surface
