Nephrostome has cilia to make coelomic fluid move into tubule. Fluid is filtered and urine passes out through nephridiopore. Metanephridia have a dense network of capillaries surrounding it- solutes are reabsorbed into the blood. Produce dilute urine. Nervous system: -Cephalization (Paired ganglia) -Nerve cords (ventral) -sense organs Respiratory/Circulatory System: Gills in aquatic organismsgills need ventilation, the flow of water over it. Molluscs use cilia on gills to ventilate. - Thickened Artery is the heart -It pumps fluid -Hemolymph -blood and body fluid cannot be distinguished -open circulatory system -Heart relaxes- draws fluid in -Body movements squeeze hemolymph through body -Squids and octopuses have closed circulatory system Include pix that show different systems Reproductive system: -Sexual -Hermaphordite Class: Polycophora Class: Gastropoda Chiton (Distinguishing features) Garden Snail (Interesting features) Stomach is foot, shows torsion twisting which causes organs to become reduced/lost and anus to come over the head (yuck!)
