Wastes are moved from blood to nephron by:

Question

Quizplus · Accepted Answer

Wastes are moved from blood to nephron by both filtration and secretion. Filtration occurs at the glomerulus, where small molecules such as waste products and excess ions are filtered from the blood into the nephron. Secretion occurs throughout the nephron, where additional waste products and excess ions are actively transported from the blood into the nephron. Reabsorption occurs primarily in the proximal tubule and loop of Henle, where essential molecules (such as glucose and amino acids) and ions (such as Na+ and HCO3-) are returned to the blood, but waste products are not reabsorbed. Therefore, the correct answer is D.
