This diagram represents the 3 structures youlearned about on the surface of a starfish.The blue structures are spines _____________ protectionfor _____________________.The red structures are ____________ Skin gillsfor Exchanging gases/removing nitrogen waste ____________________The green structure is a _____________ pedicellariafor _________________________ keeping the surface free of organisms
These are located in the ambulacral grooveTube feet Their function is ?Locomotion, suction cups can grab food,pry open clam shells, surface can exchangegases and nitrogen waste
This opening on the oral surface is the mouth _____________ This seastar is showing aboral you its ___________ surface.
This tube is the______________ Stone canal It has Calcium _______________ carbonate _______________ in it to make it hard. madreporiteIt connects the _______________________ ring canalto the ___________________
The arrow is pointing at the Ambulacral________________ ridge ___________ The part of the water vascular system that is found inside this ridge is the Radial canal ______________________ The part of the nervous system that is Radial nerve found inside is the _________________
These 3 arms farthest from the madreporite are called the_______________ trivium
This starfishis showing you its oral _____________ surface.
Tell the function of each part:Opening for water vascular system madreporite _____________________Absorb nutrients Digestive glands _____________________Connect madreporite to ring canal Stone canal ______________________Plates that fuse to form skeleton ossicles ______________________ gonadsMake sperm or eggs _________________Exchange gases and get rid of nitrogen waste Skin gills _________________
These structures that lie under the digestive glands are the gonads________________ Their function is to ____________________ Make eggs or sperm reproductive Their body system is _______________
These are located at the tip of each arm eyespotsTheir function is To sense light and dark______________________
Tell the function of each part:Keep skin free of organisms pedicellariae _____________________Extruded out through mouth during feeding Cardiac stomach ________________Stomach that connects Pyloric stomach to digestive glands ______________________Squeeze to move water up and down in tube feet ampullae _________________ spines
This white disc on the aboral surface is the madreporite ________________It belongs to the Water vascular____________________ systemIts function________________ entering the WVS Opening for water
This part of the stomach connects tothe mouthcardiac

This space aroundthe organs is the ________________ coelomType of body cavityfound in echinodermsAcoelom Pseudocoelom Eucoelom EUCOELOM
These 2 arms closest to the madreporite are called the_______________ bivium
Identify B (seen as bubbles along ambulacral ridge) B ampulla Squeeze to move water Its function is ____________________ up and down in tube feet
