What is NOT a component of the urinary system?

The liver is not a component of the urinary system, making it the correct answer. The urinary system primarily consists of organs involved in the production, storage, and elimination of urine, which includes the kidneys, bladder, ureters, and urethra.

The kidneys are responsible for filtering blood, removing waste products, and producing urine. The bladder serves as a storage reservoir for urine before it is expelled from the body. The urethra is the channel through which urine is discharged from the bladder to the outside. In contrast, the liver is part of the digestive system and plays a key role in metabolism, detoxification, and the production of biochemicals necessary for digestion, but it does not participate in urine formation or excretion.
