Now, when your body water decreases, your pituitary gland secretes antidiuretic hormone. It increases the water reabsorption, from the collecting duct. As urea is not reabsorbed from here, the water reabsorption alone, increases the urea concentration, in the lumen. So it starts getting reabsorbed at the inner medullary collecting duct. This initiates a cycle, that accumulates more and more urea, in the interstitium. This allows you to excrete urea, at higher concentrations. So the requirement for urine volume decreases. The osmolarity in the inner medulla can reach up to 1200 during this. However, urea contributes to osmolarity, only at the inner medulla. It does not contribute to osmolarity in the outer medulla, even during this. Now, when you drink enough water, the ADH level falls. Without water reabsorption, the urea does not get concentrated. So urea in the tubule is excreted in urine right away. Previously accumulated urea in the interstitium is washed out by capillaries, or, excreted in urine. During this, the osmolarity at the inner medulla falls to 600.
