urea
|
|
|
water
|
|
|
glucose

amino acids

Explanation:
Detailed explanation-1: -As the urine moves along the tubules of the nephrons, some useful substances like glucose, amino acids, salts, and water are selectively reabsorbed from it.
Detailed explanation-2: -Sodium is actively pumped out, while potassium and chloride diffuse down their electrochemical gradients through channels in the tubule wall and into the bloodstream. The walls of the thick ascending limb are impermeable to water, so in this section of the nephron water is not reabsorbed along with sodium.
Detailed explanation-3: -Urea is not reabsorbed into the blood capillaries that surround the tubule of a nephron. However, glucose, amino acid, and water are reabsorbed.
