Question

Quizplus · Accepted Answer

Excretion is the removal of substances that were filtered at the glomerulus or secreted but not reabsorbed, as they are waste products that need to be removed from the body. Choice B refers to secretion, not excretion; choice C indicates conservation, not removal; choice D is not correct, as active transport moves substances into the tubular fluid, not the urinary bladder; and choice E is not directly related to excretion.
