Which system is responsible for waste removal and balance of water in the body?

The excretory system is the primary system responsible for removing waste products and maintaining the balance of water in the body. This system includes organs such as the kidneys, ureters, bladder, and urethra, which work together to filter blood, remove waste materials, and regulate fluid levels.

The kidneys, for example, filter out toxins and excess substances, which then become urine. This urine is stored in the bladder and is expelled from the body, thereby eliminating waste. Additionally, the excretory system plays a crucial role in regulating the balance of electrolytes and water, ensuring homeostasis—a necessary condition for optimal functioning of bodily processes.

Understanding the role of the excretory system highlights its importance in overall health and the maintenance of internal balance, distinguishing it clearly from other systems that perform different functions, such as transporting blood, regulating hormones, or processing sensory information.
