Which organ system is responsible for the regulation of bodily fluids and waste removal?

The excretory system, also known as the urinary system, plays a vital role in the regulation of bodily fluids and the removal of waste. This system comprises organs such as the kidneys, ureters, bladder, and urethra. It functions by filtering blood to produce urine, which serves as a means to eliminate waste products and excess substances, such as salts and water, from the body.

One of the key processes of the excretory system is homeostasis, where it helps maintain the balance of electrolytes and the volume of fluids in the body. For example, when the body has excess water, the kidneys will excrete more urine to reduce the fluid levels, and conversely, when the body needs to conserve water, the kidneys will produce less urine.

In contrast, the other organ systems mentioned have different primary functions. The endocrine system regulates bodily functions through hormones but does not directly manage waste removal. The circulatory system is responsible for transporting blood, nutrients, gases, and waste products throughout the body but does not specifically eliminate waste. The nervous system controls and coordinates bodily activities, including reflexes and voluntary movements, but it does not handle fluid regulation or waste removal directly. Thus, the excretory system is the system specifically
