Presentation Transcript

  1. Water and Electrolyte Balance in Animals

  2. Review: Types of Transport

  3. Review: Types of Transport

  4. Review: Types of Solution

  5. Osmoregulation • Osmoconformers =

  6. Osmotic Stress in Seawater • Osmoregulators = Hypertonic environment

  7. Osmotic Stress in Freshwater Hypotonic environment

  8. Osmotic Stress in Freshwater: Salmon Chloride Cells have membrane proteins that can “flip”

  9. Osmotic Stress on Land: Insects

  10. Osmotic Stress on Land: Insects

  11. Types of Nitrogenous Wastes NH3 (ammonia) NH4+(ammonium ion) TOXIC!

  12. NH3 (ammonia)

  13. The Master of Osmoregulation: The Vertebrate Kidney

  14. Renal Corpuscle: Filtration by Size

  15. Reabsorption: The Proximal Tubule Active Transport via Protein Pumps

  16. Reabsorption: The Loop of Henle Creating an Osmotic Gradient

  17. Predict what happens to the osmotic gradient when the drug flurosemide inhibits membrane proteins that pump sodium and chloride ions out of the thick ascending limb.

  18. The Collecting Duct: Tight Control via Hormones ADH =

  19. Alcohol inhibits AHD  What impact will this have on an individual? Nicotine stimulates ADH release What impact will this have on individual?

  20. Alcohol inhibits AHD  What impact will this have on an individual? Nicotine stimulates ADH release What impact will this have on individual?

  21. The Collecting Duct: Tight Control via Hormones Aldosterone =
