  5. c. Muscle d.Nervous Figure 40.5 Figure 40.5

  6. e. Embryonic Figure 47.1

  7. Developmental stages of an Echinoderm Figure 47.7

  8. Differentiation yields endoderm, mesoderm, and ectoderm from the inner cell mass. Figure 47.16

  9. C.Systems

  10. Which body systems are involved in movement? Skeletal, Muscular, and Articular Which body systems are involved in homeostasis? Circulatory, Integumentary, Urinary, Nervous, and Endocrine Which body systems are involved in energy capture? Digestion and Respiratory Which body systems are involved in regulation? Nervous and Endocrine

  11. Which body systems are involved in reproduction? Reproductive, Nervous, and Endocrine Which body systems are involved in protection? Circulatory, Integumentary, Nervous, and Endocrine What are the body systems seen in animals? Integumentary, Skeletal, Articular, Muscular, Nervous, Endocrine, Circulatory, Excretory, Digestive, Respiratory, and Reproductive

  22. III. Animal Phyla A.Invertebrates

  23. Parazoans = Phylum Porifera Sessile adults, suspension feeders, hermaphroditic, and special cellscalled choanocytes and amebocytes

  24. Figure 33.4

  25. Radiata = Phylum Cnidarians Cnidocytes and Nematocysts

  26. Radiata = Phylum Ctenophora Comb jellies

  27. Protostomia: Lophotrochozoa = Phylum Platyhelminthes Flat worms Figure 33.10 Figure 33.12
