A nephron is the functional unit of the kidney, responsible for filtering blood and producing urine. Each nephron consists of a glomerulus, where blood filtration occurs, and a renal tubule, where reabsorption and secretion take place. As blood passes through the glomerulus, waste and excess substances are removed, while essential nutrients and water are reabsorbed back into the bloodstream. This process helps regulate fluid balance, electrolyte levels, and waste elimination in the body.
