Question

Quizplus · Accepted Answer

Tubular secretion refers to the process of selectively moving substances from the blood to the tubular fluid in the kidneys. This process eliminates certain unwanted substances that were not filtered out of the blood during the process of glomerular filtration. Therefore, the correct choice is C, in which unwanted substances are moved from the blood to the tubular fluid. Option A and B are incorrect because they refer to the movement of nutrients, which occurs in the opposite direction, from the tubular fluid to the blood. Option D is also incorrect because it refers to the movement of nutrients, rather than unwanted substances.
