  1. AMPHIBIANS HOLT BIOLOGY CH. 30 Pg. 739-750

  2. CHARACTERISTIC OF AMPHIBIANS • LEGS (most)

  3. CHARACTERISTIC OF AMPHIBIANS • LEGS (most) • LUNGS

  4. CHARACTERISTIC OF AMPHIBIANS • LEGS (most) • LUNGS • DOUBLE-LOOP CIRCULATION

  5. CHARACTERISTIC OF AMPHIBIANS • LEGS (most) • LUNGS • DOUBLE-LOOP CIRCULATION • PARTIALLY DIVIDED HEART

  6. CHARACTERISTIC OF AMPHIBIANS • LEGS (most) • LUNGS • DOUBLE-LOOP CIRCULATION • PARTIALLY DIVIDED HEART • CUTANEOUS (skin) RESPIRATION • Live on land, but must stay close to water

  7. MOVEMENT AND RESPONSE • Strong endoskeleton needed to support gravity on land

  8. MOVEMENT AND RESPONSE • Strong endoskeleton needed to support gravity on land • Good sense of hearing and sight

  9. MOVEMENT AND RESPONSE • Strong endoskeleton needed to support gravity on land • Good sense of hearing and sight • Hunting

  10. MOVEMENT AND RESPONSE • Strong endoskeleton needed to support gravity on land • Good sense of hearing and sight • Hunting • Avoid predators

  11. MOVEMENT AND RESPONSE • Strong endoskeleton needed to support gravity on land • Good sense of hearing and sight • Hunting • Avoid predators • Eye covered in third eyelid (NICTITATING MEMBRANE)

  12. MOVEMENT AND RESPONSE • Strong endoskeleton needed to support gravity on land • Good sense of hearing and sight • Hunting • Avoid predators • Eye covered in third eyelid (NICTITATING MEMBRANE) • Inner ear detects sound transmitted through TYMPANIC MEMBRANE-vibration sent through fluid, tiny sensitive hairs then to nerves

  13. RESPIRATION • Amphibians get oxygen from

  14. RESPIRATION • Amphibians get oxygen from • Skin

  15. RESPIRATION • Amphibians get oxygen from • Skin • Lungs

  16. RESPIRATION • Amphibians get oxygen from • Skin • Lungs • Mouth

  17. RESPIRATION • Amphibians get oxygen from • Skin • Lungs • Mouth • LUNGS

  18. RESPIRATION • Amphibians get oxygen from • Skin • Lungs • Mouth • LUNGS • Larval state has gills

  19. RESPIRATION • Amphibians get oxygen from • Skin • Lungs • Mouth • LUNGS • Larval state has gills • Most adults breathe with lungs

  20. RESPIRATION • Amphibians get oxygen from • Skin • Lungs • Mouth • LUNGS • Larval state has gills • Most adults breathe with lungs • Bag-like organ that allows for exchange of oxygen and carbon dioxide

  21. RESPIRATION • Amphibians get oxygen from • Skin • Lungs • Mouth • LUNGS • Larval state has gills • Most adults breathe with lungs • Bag-like organ that allows for exchange of oxygen and carbon dioxide • Great surface area (due to folds in tissue)

  22. RESPIRATION • Amphibians get oxygen from • Skin • Lungs • Mouth • LUNGS • Larval state has gills • Most adults breathe with lungs • Bag-like organ that allows for exchange of oxygen and carbon dioxide • Great surface area (due to folds in tissue) • Lower bottom jaw to draw air in, lift lower jaw to force waste gas out

  23. RESPIRATION • Amphibians get oxygen from • Skin • Lungs • Mouth • LUNGS • Larval state has gills • Most adults breathe with lungs • Bag-like organ that allows for exchange of oxygen and carbon dioxide • Great surface area (due to folds in tissue) • Lower bottom jaw to draw air in, lift lower jaw to force waste gas out • 20 times more oxygen than water

  24. RESPIRATION • SKIN (CUTANEOUS BREATHING)

  25. RESPIRATION • SKIN (CUTANEOUS BREATHING) • Skin is thin and moist

  26. RESPIRATION • SKIN (CUTANEOUS BREATHING) • Skin is thin and moist • Gases passed right through skin

  27. RESPIRATION • SKIN (CUTANEOUS BREATHING) • Skin is thin and moist • Gases passed right through skin • Mucous glands help keep skin moist

  28. CIRCULATION • More efficient than fish

  29. CIRCULATION • More efficient than fish • PARTIALLY DIVIDED HEART

  30. CIRCULATION • More efficient than fish • PARTIALLY DIVIDED HEART • SEPTUM (wall) divides top (ATRIA) of heart

  31. CIRCULATION • More efficient than fish • PARTIALLY DIVIDED HEART • SEPTUM (wall) divides top (ATRIA) of heart • Blood MIXES (oxygen rich and oxygen poor) in VENTRICLES

  32. CIRCULATION • More efficient than fish • PARTIALLY DIVIDED HEART • SEPTUM (wall) divides top (ATRIA) of heart • Blood MIXES (oxygen rich and oxygen poor) in VENTRICLES • SEE PG. 742 DIAGRAM

  33. CIRCULATION • More efficient than fish • PARTIALLY DIVIDED HEART • SEPTUM (wall) divides top (ATRIA) of heart • Blood MIXES (oxygen rich and oxygen poor) in VENTRICLES • SEE PG. 742 DIAGRAM • Ventricle contracts and sends blood to vessels of rest of body

  34. CIRCULATION • DOUBLE LOOP CIRCULATION

  35. CIRCULATION • DOUBLE LOOP CIRCULATION • See pg. 743 (compare fish to amphibians)

  36. CIRCULATION • DOUBLE LOOP CIRCULATION • See pg. 743 (compare fish to amphibians) • PULMONARY VEINS-carry oxygen rich blood from lungs to heart

  37. CIRCULATION • DOUBLE LOOP CIRCULATION • See pg. 743 (compare fish to amphibians) • PULMONARY VEINS-carry oxygen rich blood from lungs to heart • Second loop carries oxygen rich blood from heart to body

  38. CIRCULATION • DOUBLE LOOP CIRCULATION • See pg. 743 (compare fish to amphibians) • PULMONARY VEINS-carry oxygen rich blood from lungs to heart • Second loop carries oxygen rich blood from heart to body • High pressure
