Study Notes

Animal Kingdom Classifications

  • Vertebrates have a backbone
  • Invertebrates do not have a backbone
  • Pseudocoelomates are a type of invertebrate with a pseudocoelom, a fluid-filled cavity between the endoderm and mesoderm
  • Acoelomates are a type of invertebrate without a true body cavity

Body Structure

  • Endoskeleton: internal structure of bone
  • Exoskeleton: tough plate on the outside of the body

Life Processes

Nutrition

  • Ingestion: intake of food
  • Digestion: breaking down of food
  • Assimilation: absorbing nutrients
  • Elimination: expelling wastes

Movement and Locomotion

  • Motile: able to move around
  • Sessile: stationary

Respiration

  • Exchanging oxygen and carbon dioxide

Circulatory Systems

  • Open Circulatory System: hemolymph flows from vessels into the body cavity
  • Closed Circulatory System: blood is contained in vessels

Reproduction

  • Asexual reproduction: budding and regeneration
  • Sexual reproduction: involving sex cells

Response to Stimuli

  • Stimuli: external factors that elicit a response
