MICROANATOMY

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

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 occurs when the kidneys reabsorb useful substances, such as glucose, amino acids, and electrolytes, from the filtrate back into the bloodstream. This process occurs primarily in the proximal tubule of the nephron and is critical in maintaining the body’s electrolyte and fluid balance.
