lo 6.3. what is the reabsorption process?
the movement of useful substances from the filtrate back into the blood
the process by which the kidneys produce urine
the process by which substances are removed from the blood and eliminated from the body
the transfer of substances from the blood into the filtrate
the movement of useless substances from the filtrate back into the blood

Explanation:

Reabsorption in the kidneys is about taking useful substances (like glucose, amino acids, water, and electrolytes) from the filtrate (which is formed after filtration in the glomerulus) and sending them back into the bloodstream. The other options are incorrect. The process by which kidneys produce urine involves filtration, reabsorption, and secretion. The process of removing substances from blood and eliminating them from the body is more about excretion (after reabsorption of useful substances). The transfer of substances from blood into filtrate is filtration. And moving useless substances from filtrate back to blood is not a normal physiological process (as we want to excrete waste, not reabsorb it).

Answer:

The movement of useful substances from the filtrate back into the blood
