  5. 5. Circulatory System Functions <ul><li>Have a two chambered heart </li></ul><ul><li>Pumps blood throughout the body </li></ul><ul><li>Makes sure blood is oxygenated </li></ul><ul><li>Arteries and veins work together in order to supply blood throughout the sharks body </li></ul>
  6. 6. Nervous System <ul><li>Summary </li></ul><ul><li>Pictures </li></ul><ul><li>Function </li></ul><ul><li>Skeleton System </li></ul>
  7. 7. Nervous System Summary <ul><li>Shark is made up of: </li></ul><ul><li>Brain </li></ul><ul><li>Spinal Cord </li></ul><ul><li>Peripheral Nervous System </li></ul><ul><li>Sense organs </li></ul><ul><li>Cranial Nerves: Nerves that carry impulses to the brain, nerves that control senses of sharks: smell, touch, hear, etc. </li></ul>
  8. 8. Nervous System Pictures
  9. 9. Nervous System Function <ul><li>Controls the sharks behavior </li></ul><ul><li>Controls sharks senses: Sight, touch, hearing, smell, taste </li></ul>
  10. 10. Skeleton System <ul><li>Summary </li></ul><ul><li>Pictures </li></ul><ul><li>Function </li></ul><ul><li>Digestive System </li></ul>
  11. 11. Skeleton Summary <ul><li>The skeleton of the shark is not made of bones, it is made of cartilage extremely light to help with speed </li></ul>
  12. 12. Skeleton System Labels rostrum Orbit Gill Arches Fin cartilage Rib cartilage Vertabrate
  13. 13. Function <ul><li>The orbit is used to hold the eye in place </li></ul><ul><li>Rostrum used to take in water to flow over the gills and make the shark breath </li></ul><ul><li>Gill arches are to keep the gills open for water to be released </li></ul><ul><li>Fin cartilage is used to help keep the shark floating </li></ul>
  14. 14. Digestive System <ul><li>Summary </li></ul><ul><li>Labels </li></ul><ul><li>Function </li></ul><ul><li>External System </li></ul>
  15. 15. Digestive Summary <ul><li>The shark digestive system is used to process food and pass the nutrients through its body. </li></ul>
  16. 16. Digestive System Labels
  17. 17. Digestive System Functions <ul><li>Mouth is used to take in food </li></ul><ul><li>Esophagus is used to transport food to the stomach </li></ul><ul><li>Stomach is used to break down food in to nutrients </li></ul><ul><li>Liver is used to help the shark float and take out poisonous toxins from the food </li></ul><ul><li>Intestines spreads nutrients around body and waste out of the body </li></ul>
  18. 18. External <ul><li>Summary </li></ul><ul><li>Photo </li></ul><ul><li>Labels </li></ul><ul><li>Functions </li></ul><ul><li>Muscular System </li></ul>
  19. 19. External Summary <ul><li>Cut the dorsal sine </li></ul><ul><li>Then we cut a straight line down the belly </li></ul><ul><li>Cut again under the mouth horizontal </li></ul><ul><li>Anther cut before the anal fins </li></ul><ul><li>Then we open wide </li></ul>

  22. 22. External Function <ul><li>The Body is rough and feel with lots of teeth like scale. </li></ul><ul><li>The nostril is only use to breath </li></ul><ul><li>The Gills are used to breath </li></ul><ul><li>Pectoral Fins are used to turn left and right </li></ul><ul><li>The eye are used to see </li></ul><ul><li>The Fins are mainly used to steer </li></ul>
  23. 23. Muscular System <ul><li>Summary </li></ul><ul><li>Labels </li></ul><ul><li>Function </li></ul>
  24. 24. Muscular System Summary <ul><li>The muscular system is the system for strength and push that the shark has. </li></ul><ul><li>The system helps move the tail for the sharks speed and shape turns. </li></ul><ul><li>There are muscular parts like: Branchiomeric Muscles, Axial Muscles, Appendicular Muscles, Eye Muscles </li></ul>
  25. 25. Muscle Label
  26. 26. The Muscular System Function <ul><li>Preorbitalis –It helps in opening the jaw. </li></ul><ul><li>Adductor Mandibulae –are the main muscles in closing the jaw. </li></ul><ul><li>Levator Palatoquadrati – it helps raise the jaw. </li></ul><ul><li>Intermandibularis –it assists in jaw closing. </li></ul><ul><li>Levator Hyomandibulae –this muscle raises the jaw. </li></ul><ul><li>Hyoid Constrictor – it acts to constrict the gill cavity. </li></ul><ul><li>Ventral Constrictors –These also constrict the gill cavities. </li></ul><ul><li>Dorsal Constrictors –These also constrict the gill cavities. </li></ul><ul><li>Septal Constrictors – Constricts the caudal gill cavity. </li></ul><ul><li>Pectoral Levators – they raise the pectoral fin. </li></ul><ul><li>Cucullaris – this muscle moves the pectoral fin dorsally and crainally. </li></ul>
