Question

what is nephron what is its role in the Kidney ​

Answer 1

A nephron is the basic structural and functional unit of the kidneys that regulates water and soluble substances in the blood by filtering the blood, reabsorbing what is needed, and excreting the rest as urine. Its function is vital for homeostasis of blood volume, blood pressure, and plasma osmolarity.

Their basic functions include:

• Regulation of extracellular fluid volume. The kidneys work to ensure an adequate quantity of plasma to keep blood flowing to vital organs.
• Regulation of osmolarity.
• Regulation of ion concentrations.
• Regulation of pH.
• Excretion of wastes and toxins.
• Production of hormones.

The primary function of the nephron is to remove waste products from the body before they build up to toxic levels. The nephron does its job of getting rid of metabolic wastes through filtration and secretion. Useful substances are reabsorbed back into the blood.
