What organs compose the urinary system?

The urinary system is responsible for filtering and eliminating waste products from the body, and consists of the kidneys, ureters, bladder, and urethra. These organs work together to remove excess water, salts, and toxins from the blood, which are then excreted as urine. Option A is incorrect because the liver, gallbladder, and pancreas are all part of the digestive system, not the urinary system. Option C is incorrect because the heart, arteries, veins, and capillaries make up the cardiovascular system, not the urinary system. Option D is also incorrect because the stomach, esophagus, intestines, and rectum are all part of the digestive system, not the urinary system.
