Verified step by step guidance

Step 1: Begin by understanding the primary functions of the urinary system. The urinary system is responsible for filtering blood, removing waste products, regulating electrolyte balance, and maintaining fluid homeostasis.

Step 2: Review the roles of each organ in the urinary system: ureters transport urine from the kidneys to the bladder, the urinary bladder stores urine, and the urethra is the tube through which urine exits the body.

Step 3: Focus on the kidneys, as they are the organs responsible for performing major homeostatic functions. These include filtering blood to remove waste, regulating blood pressure, balancing electrolytes, and maintaining acid-base balance.

Step 4: Compare the functions of the kidneys to the other organs listed in the question. The ureters, urinary bladder, and urethra primarily serve as structures for urine transport and storage, not homeostasis.

Step 5: Conclude that the kidneys are the correct answer because they perform the major homeostatic functions in the urinary system, such as filtration, regulation, and balance.
