The medical term “renal” refers to what?

The term “renal” refers to the kidneys, vital organs responsible for filtering waste products and excess fluids from the blood to form urine. The word originates from the Latin renalis, meaning “of the kidneys.” Renal health is essential for maintaining electrolyte balance, blood pressure, and red blood cell production. Common renal-related conditions include renal failure, renal stones, and renal hypertension. Doctors specializing in kidney function are called nephrologists. Maintaining hydration, a balanced diet, and monitoring blood pressure are key to supporting renal health and preventing chronic kidney diseases.
