36. What advantages does segmentation provide?
Better movement…segments can move
independently, rather than whole animal having
to move at once
Repeat of vital organs, e.g. several hearts,
nephridia, reproductive organs, so if some are
injured, organism does not die

Flukes…flatworms, live in blood, intestines, liver, lungs …
block blood vessels (e.g. schistosomiasis)
Tapeworm…flatworm, intestines, absorbs food
Ascaris…roundworm…intestines, lungs throat…block air
passages
Hookworms…roundworm…intestines…feed on blood
Trichinella...roundworm, muscle…muscle pain, stiffness
Pinworm…roundworm…lower intestine…no real harm
