Los riñones

The video explains the kidneys' role in maintaining fluid balance in the body. Located below the ribs, kidneys filter blood, removing excess salts, water, and urea to form urine. Blood enters through the renal artery and exits via the renal vein. Nephrons, the kidney's microscopic structures, perform the filtration. Urine travels to the bladder through the ureter. The kidneys also communicate with the brain to balance urine production with fluid intake and loss, ensuring homeostasis.
