Detailed explanation-1: -Tubular reabsorption is the process that moves solutes and water out of the filtrate and back into your bloodstream.

Detailed explanation-2: -Glucose, amino acids, NaCl and other essential salts are reabsorbed in the second step of urine formation i.e Tubular Reabsorption. These essential substances are filtered from blood in the first step called glomerular filtration and are reabsorbed as they are vital for body function.

Detailed explanation-3: -Most of the reabsorption of solutes necessary for normal body function such as amino acids, glucose, and salts takes place in the proximal part of the tubule. This reabsorption may be active, as in the case of glucose, amino acids, and peptides, whereas water, chloride, and other ions are passively reabsorbed.

Detailed explanation-4: -From the glomerulus filterate glucose, salts, vitamins, water and other useful substances are selectively reabsorbed by the tubule and sent back into the blood.
