Question

Which of the following is a correct statement about nephrons?

Materials such as urea and water are filtered out of the blood in the glomerulus, but glucose is reabsorbed out of the blood by the renal tubules.
Materials such as glucose and water are reabsorbed out of the blood in the glomerulus, but urea is filtered out of the blood by the renal tubules.
Materials such as urea, water, and glucose are reabsorbed out of the blood in the glomerulus, and water and glucose are then filtered back into the blood by the renal tubules.

Answer 1

Materials such as urea, water, and glucose are filtered out of the blood in the glomerulus, and water and glucose are then reabsorbed into the blood by the renal tubules.

Step-by-step explanation:

The correct statement about nephrons is: Materials such as urea, water, and glucose are filtered out of the blood in the glomerulus, and water and glucose are then reabsorbed into the blood by the renal tubules.

The glomerulus filters materials like urea, water, and glucose out of the blood, while the renal tubules reabsorb water and glucose back into the blood. This process helps maintain proper balance of substances in the body. An example of this process occurs in the kidneys, where glucose, water, salts, ions, and amino acids needed by the body are filtered and reabsorbed in different parts of the nephron.

Answer 2

Materials such as urea, water, and glucose are filtered out of the blood in the glomerulus, and water and glucose are then reabsorbed into the blood by the renal tubules.

Step-by-step explanation:

A pair of Kidneys is the principal excretory organ of the humans. Each kidney is composed of millions of its unit called nephrons. The nephron is the functional unit of the kidney as it filters out urea, water, and glucose from the bloodstream through the process of ultrafiltration. The filtered out material is called nephric filtrate. The filtrate then moves various tubules, called renal tubules where important molecules such as glucose, ions and water are reabsorbed into the blood.
