What organs are part of the urinary system?

The urinary system is specifically responsible for the production, storage, and elimination of urine, which is a primarily composed of waste products filtered from the blood. The main organs involved in this system are the kidneys, ureters, urinary bladder, and urethra.

The kidneys play a crucial role in filtering blood and producing urine. Once urine is formed, it travels through the ureters—two tubes that connect each kidney to the urinary bladder. The bladder serves as a storage reservoir for urine until it is ready to be expelled from the body through the urethra. This system works in unison to maintain water balance, electrolyte levels, and the body's overall homeostasis.

Other options include organs that belong to different systems. The first option lists components of the cardiovascular and respiratory systems, which are unrelated to urine formation or elimination. The third option includes organs of the digestive system, which have functions divided between processing food and nutrient absorption. The final option mentions parts of the central nervous system, which are responsible for processing information and directing bodily functions but do not have a role in urine production or excretion.

In summary, the correct answer highlights the specific organs integral to the urinary system's structure and function.
