PATHOLOGY

Detailed explanation-1: -Tubular reabsorption is the movement of substances into the blood from the filtrate.

Detailed explanation-2: -Tubular reabsorption is a passive process whereby drugs are reabsorbed into the systemic circulation from the lumen of the distal tubules. As with enteral absorption, only un-ionized molecules are available for reabsorption.

Detailed explanation-3: -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.
