ANATOMY

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: -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: -in which direction do substances move during tubular reabsorption? from the tubular fluid into the blood.

Detailed explanation-5: -The term for the active transport of substances from blood into the filtrate is secretion. Secretion occurs along the nephron and is opposed by reabsorption, which is where substances are put back into the blood.
