What is the function of nephron class 10?

The nephron is the basic functional unit of the kidney - think of it as the kidney's "worker" that actually performs the kidney's job. Here are its main functions:

Primary functions: 1. Filtration - Removes waste products from blood 2. Reabsorption - Takes back useful substances the body needs 3. Secretion - Adds additional wastes to the filtrate 4. Urine formation - Produces the final urine that gets excreted

Simple analogy: Imagine a recycling center where: - Everything comes in mixed together (blood) - Useful items are sorted and kept (reabsorption) - Trash is separated and removed (filtration and secretion) - The waste is packaged for disposal (urine formation)

Each kidney contains about 1 million nephrons working constantly to clean your blood. They help maintain the body's water balance, electrolyte levels, and blood pressure while removing toxins like urea and creatinine.

Understanding nephrons is key to understanding how kidneys work and why kidney failure is so serious - without functioning nephrons, wastes build up in the body!
