Presentation Transcript

  1. Osmoregulation & Excretion

  2. Osmoregulation • Osmosis between organisms and environment • Stenohaline: can't tolerate extreme changes in external osmolarity • Euryhaline: can survive changes

  3. Osmoconformers • Are iso-osmotic with their environment

  4. Osmoregulators • Can control their internal osmolarity independent of their environment

  5. Nitrogenous Waste

  6. Excretory Processes

  7. Flatworms

  8. Earthworms

  9. Insects

  10. Humans Excretory Organs

  11. Kidneys

  12. Types of Nephrons

  13. Nephron Organization

  14. Blood Filtrate to Urine

  15. Kidney Summation • Requires a lot of energy • Helps to conserve more water, and essential nutrients

  16. Managing Osmoregulatory Function of Kidney • Nervous system and endocrine system help manage kidneys • antidiuretic hormone (ADH)

  17. Renin-Angiotensin-Aldosterone System

  18. Gout • Uric acid build-up in joints • Symptoms: • sudden joint pain • acute joint tenderness and redness • Causes: • body makes too much uric acid • body is unable to dispose of uric acid • Treatment • painkillers • Daily use of allopurinol or probenecid (decreases uric acid levels in your blood)

  19. Kidney Stones • solid mass of small crystals • Symptoms: • Pain in belly area, side of back, groin • blood in urine • nausea • Causes: • build-up of substance in urine which creates crystals that turn into stones • Treatments: • medication • Extracorporeal shock-wave lithotripsy • Percutaneous Nephrolithotomy
