Reabsorption

 

reverse absorption of water and substances dissolved in it from primary urine flowing through the renal tubules; the final urine thus produced is excreted from the body. Among the essential substances that are reabsorbed are many amino acids, vitamins, and most Na+, K+, and Ca2+ions. The reabsorption of some substances varies with their concentration in the blood. For example, glucose is completely reabsorbed if its concentration in plasma is no more than 150–180 mg percent. At high concentrations, some of the glucose enters the urine (glucosuria).
