During hypovolemia, when levels of vasopressin are high and water is maximally reabsorbed, the inner medullary interstitial fluid urea concentration concomitantly rises, owing to the increased concentration gradient for the passive transport of urea out … " - Passive reabsorption

Passive reabsorption

WebPassive transport requires no expenditure of energy. This is because molecules have the tendency to move from areas of high concentration to areas of low concentration. This can be through a partially permeable membrane. An example of this is when toast begins to burn and the smoke moves throughout the house and can be smelt strongly.
