if the concentration of solutes(salts, sugars, ions) in the blood rises above a certain level then what happens in the kidney tu
Sliva [168]
The answer is: more water will be reabsorbed in the kidney tubules.

Kidney tubules are the part of a nephron, a basic unit of function and structure of the kidney. The function of nephrons is secretion and reabsorption of a variety of solutes. If the concentration of solutes in the blood rises above certain level, this is a signal for kidney tubules to reabsorbe water. With more water in the blood now, the concentration of solute will reduce.
