MICROANATOMY

Detailed explanation-1: -Substances such as glucose and amino acids, useful to the body are reabsorbed from the tubule in the proximal tubule. Proximal tubule is the portion of the nephron that lies between Bowman’s capsule and the loop of Henle.

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: -Tubular reabsorption is the second major step in urine formation. 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.
