2 CHARACTERISTICS OF FISH ENDOSKELETON

3 CHARACTERISTICS OF FISH ENDOSKELETON GILLS

4 CHARACTERISTICS OF FISH ENDOSKELETON GILLS CLOSED-LOOP CIRCULATORY SYSTEM

6 MOVEMENT/RESPONSE ENDOSKELETON-internal skeleton- muscles attach

7 MOVEMENT/RESPONSE ENDOSKELETON-internal skeleton- muscles attach FINS AND SWIM BLADDER

8 MOVEMENT/RESPONSE ENDOSKELETON-internal skeleton- muscles attach FINS AND SWIM BLADDER Fins increase stability (turn, dive, climb rapidly)

15 RESPIRATION/CIRCULATION Get oxygen from water (GILLS)

16 RESPIRATION/CIRCULATION Get oxygen from water (GILLS) OPERCULUM-gill cover

17 RESPIRATION/CIRCULATION Get oxygen from water (GILLS) OPERCULUM-gill cover COUNTERCURRENT FLOW-

18 RESPIRATION/CIRCULATION Get oxygen from water (GILLS) OPERCULUM-gill cover COUNTERCURRENT FLOW- Water passes over gills in one direction, blood flows opposite direction (85% of dissolved O2 passes over gills)

19 RESPIRATION/CIRCULATION Get oxygen from water (GILLS) OPERCULUM-gill cover COUNTERCURRENT FLOW- Water passes over gills in one direction, blood flows opposite direction (85% of dissolved O2 passes over gills) SINGLE LOOP BLOOD CIRCULATION

20 RESPIRATION/CIRCULATION Get oxygen from water (GILLS) OPERCULUM-gill cover COUNTERCURRENT FLOW- Water passes over gills in one direction, blood flows opposite direction (85% of dissolved O2 passes over gills) SINGLE LOOP BLOOD CIRCULATION Blood->gills->heart (atrium then ventricle)- >pumped body->gills

21 EXCRETION Most vertebrates conserve water (2/3 of body is water)
