renal units

Renal units, also known as nephrons, are the functional building blocks of the kidneys. Each kidney contains about a million nephrons that filter blood, remove waste products, and regulate water, salt, and other vital substances. This process helps maintain your body's fluid balance, control blood pressure, and produce urine. Think of each renal unit as a tiny, specialized filter working together to keep your internal environment healthy and stable. The efficiency of these units determines overall kidney health and function.
