Answer to Question 1
Consisting of the kidneys, ureters, urinary bladder, and urethra, the urinary system has three primary functions: (1 ) excretion, the removal of organic waste products from body fluids, (2 ) elimination, the discharge of these waste products into the environment, and (3 ) homeostatic regulation of the volume and solute concentration of blood plasma. The excretory and homeostatic regulation functions of the urinary system are performed by the two kidneys that produce urine, a fluid containing water, ions, and small soluble compounds. Urine leaving the kidneys flows along paired tubes called ureters to the urinary bladder, a muscular sac for temporary storage of urine. On being forced out of the urinary bladder, urine passes through the urethra to the exterior. The urinary bladder and the urethra are responsible for the elimination of urine, a process called urination or micturition.
