  • Step 3: Increased Metabolic wastes are due to inadequate Reabsorption.
  • Step 4: The presence of vital Vitamins in urine is due to inadequate Reabsorption.

Thus, Step 1 belongs to filtration, Step 2 belongs to secretion, and Steps 3 and 4 belong to reabsorption.

<h3>What is the important function of Nephron?</h3>

The important function of the nephron may include the removal of all waste products through urine, secretion of numerous substances, excess water from the blood, etc.

Therefore, it is well described above.
