Reabsorption takes place mainly in the proximal convulated tubule of the nephron, nearly all of the water, glucose, potassium, and amino acids lost during glomerular filtration re-enter the blood from the renal tubules,moving solutes out of the filtrate and back into the bloodstream.these solutes that are moved back into the bloodstream goes back into circulation alongside with the blood because it is needed for the normal functioning of the body system and maintanance of homeostasis.

In a situation where tubular reabsorption does not occur as a result of certain conditions like hyposecretion and diabetes insipidus,there will be imbalance of ions in the body as a result of useful ions leaving the body via urine and the body is left with ion deficiency.
