About Kidney Tubules
- The kidney tubules are affected by anti-diuretic hormone.
- When there is not enough water in the blood the pituitary gland secretes anti-diuretic hormone which causes the tubules to allow water back into the blood.
- When there is too much water in the blood the pituitary gland stops secreting anti-diuretic hormone which causes the tubules to stop allowing water back into the blood.
