Description: Introduces organization and functions of the flatworm body, and illustrates the advance it represents over the more primitive coelenterates. Regeneration demonstrations with planarias illustrate the principles of polarity, anterior-posterior gradient, and dominance., Describes several varieties of flatworms illustrating some of their differences, their habitat, and their characteristics. Discusses their sense organs, muscles, nervous system, digestive and excretory systems, and regenerative qualities. Uses several experiments to illustrate the principle of regeneration.
