Answer

Answer:

C. Some of the materials that exit the blood can be returned to the blood.

Brief Explanations:

In the nephron, filtration occurs first where blood components move from the glomerulus into the Bowman's capsule. Then, during re - absorption, many useful substances like glucose, amino acids, and some water that have left the blood are returned back to the blood through the peritubular capillaries surrounding the renal tubules. Option A is incorrect as blood is filtered in the nephron but not removed through the urethra. Option B is wrong because not all substances that enter the nephron are excreted in urine; re - absorption occurs. Option D is incorrect as normal urine has very little sugar, and water re - absorption helps maintain body fluid balance.
