Functions: Processes and digests food, absorbs and conserves water, absorbs nutrients, stores energy reserves
Explain the major organs and functions of the urinary system?
Major Organs: Kidneys, Ureters, Urinary bladder, Urethra
Functions: Excretes waste products from the blood, Controls water balance by regulating volume of urine produced, stores urine prior to voluntary elimination, regulates blood ion concentrations and pH
