Sodium |
|
|
|
The reabsorption of sodium in the distal tubule is under the influence of two hormones:
|
Potassium |
|
|
|
Aldosterone acts of the sodium/potassium ATPase in the principal cells of the collecting duct increase potassium excretion. |
Urea |
|
|
|
ADH makes the collecting duct more permeable to Urea |
H+ and HCO3- |
|
|
||
Glucose |
|
|||
Protein |
|
|||
Calcium |
|
|
The regulation of how much calcium is reabsorbed occurs in the athe distal tubule and collecting ducts. | Parathyroid hormone stimulates reabsorption. |
