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.
