Osmoregulation & Excretion
• Osmosis between organisms and environment
• Stenohaline: can't tolerate extreme changes in external osmolarity
• Euryhaline: can survive changes
Osmoregulation
Osmoconformers• Are iso-osmotic with their environment
Osmoregulators• Can control their internal osmolarity
independent of their environment
Nitrogenous Waste
Excretory Processes
Flatworms
Earthworms
Insects
HumansExcretory Organs
Kidneys
Types of Nephrons
Nephron Organization
Blood Filtrate to Urine
Kidney Summation• Requires a lot of energy• Helps to conserve more water, and essential
nutrients
Managing Osmoregulatory Function of Kidney
• Nervous system and endocrine system help manage kidneys
• antidiuretic hormone (ADH)
Renin-Angiotensin-Aldosterone System
Gout• Uric acid build-up in joints• Symptoms:
o sudden joint paino acute joint tenderness and redness
• Causes:o body makes too much uric acido body is unable to dispose of uric acid
• Treatmento painkillerso Daily use of allopurinol or probenecid (decreases uric acid
levels in your blood)
Kidney Stones• solid mass of small crystals• Symptoms:
o Pain in belly area, side of back, groino blood in urineo nausea
• Causes:o build-up of substance in urine which creates crystals that turn into
stones
• Treatments:o medication o Extracorporeal shock-wave lithotripsyo Percutaneous Nephrolithotomy
