The urinary system lies in the abdominal and pelvic cavities. The kidneys also can adjust blood volume though mechanisms that draw water out of the filtrate and urine.

The kidneys make urine by filtering wastes and extra water from blood. [4] Vasopressin increases water permeability of the kidney's collecting duct and distal convoluted tubule by inducing translocation of aquaporin-CD water channels in the kidney nephron collecting duct plasma membrane.[5].
