What role does a nephron play in the human body?

The nephron plays a crucial role in the human body by filtering blood to form urine. This process is essential for maintaining the body’s fluid balance, electrolyte levels, and the removal of waste products. Each nephron consists of different structures, including the glomerulus, which filters blood, and the renal tubule, where reabsorption and secretion occur. By performing these functions, nephrons help ensure that waste products and excess substances are eliminated from the body efficiently, thus playing a vital role in homeostasis.

Understanding the role of the nephron highlights its importance in kidney function and overall health, as dysfunction in this process can lead to various medical conditions, including kidney diseases.
