nephron

A nephron is the basic functional unit of the kidney, responsible for filtering blood and producing urine. Each kidney contains about a million nephrons. Blood flows into the nephron, where tiny blood vessels and filtering structures remove waste products, excess salts, and water. The process results in the formation of urine, which is then collected and transported to the bladder. Nephrons also help regulate blood pressure, electrolyte levels, and pH balance, maintaining overall body health. They work continuously to cleanse the blood, ensuring the body's internal environment stays stable.
