Quizplus · Accepted Answer

Tubular reabsorption is the process by which the nephron moves certain chemicals from the tubular fluid back into the blood. This includes ions, nutrients, and water that are needed by the body. Glomerular filtration is the initial process by which blood is filtered into the tubular system, but it does not involve the movement of substances back into the blood. Tubular secretion is the process by which the nephron removes certain chemicals from the blood and adds them to the tubular fluid. Therefore, the correct answer is B.
