Name the substances other than water, that are reabsorbed during urine formation. What are the two parameters that decide the amount of water that is reabsorbed in the kidney?



Glucose , amino acids , other nutrients , salts and a lot of water are selectively re-absorbed as the urine flows through the tubule

The amount of water reabsorbed depends on:

  • Amount of excess water in the body - If the body already has a high amount of water , less water will be re-absorbed in the tubule and vice versa.
  • Amount of dissolved waste to be excreted - Tubules re-absorb large quantity of water if amount of waste in body is high
