Important Questions on Animal Kingdom








\n\n
The digestive systems of different animals have been classified into two types based on their complexity: incomplete and complete. Platyhelminthes have an incomplete digestive system, with only a single opening to the outside of the body, that serves both as mouth and anus. Other members possessing such a digestive tract include the Coelenterates and Ctenophores. Roundworms (Ascaris) and echinoderms (Asterias) possess a complete digestive system. This type of system has two openings; mouth for the intake of food and anus for the elimination of faecal matter. Hence, the entry of food and exit of waste takes place from separate openings. Sponges (Spongilla) show intracellular digestion. The food particles are taken up by the choanocytes of the sponges and digested in the food vacuoles within them.
