REABSORPTION

• HOW IS IT REABSORBED?

  1. Large molecules remain in capillaries
  2. Creates a lowered water potential
  3. Towards the venule end of capillaries, hydrostatic pressure is lowered due to the loss of liquid
  4. Water potential is very low
  5. Water re-enters capillaries by osmosis
• WHY IS PRESSURE LOWERED IN THE VENULE END OF CAPILLARIES?

  loss of liquid
• WHY CAN REABSORPTION OCCUR?

  osmotic pressure exceeds hydrostatic pressure
