- The Kidneys
- Ultraflitration
- 2) High pressure squeezes water, urea, salts + glucose into Bowman's capsule (through membrane)
- 3) Filtered liquid = glomerular filtrate
- Reabsorption
- 1) All glucose reabsorbed
- Proximal convulated tube
- Active transport
- 2) Sufficient salt reabsorbed
- 3) Sufficient water reabosorbed
- Collecting duct
- 1) All glucose reabsorbed
- Release of wastes
- Remaining substances form urine
- Water, salt + urea
- Continues out of nephron + into bladder
- Released via urethra
- Remaining substances form urine
- Osmoregulation
- Antidiuretic hormone (ADH) controls water content
- Makes nephron wall more permeable
- Made in pituitary gland
- Brain monitors water content of blood
- If water content too high or low, negative feedback mechanism triggers back to normal
- Antidiuretic hormone (ADH) controls water content
- Ultraflitration
