Excretory System
The excretory system plays a vital role in maintaining homeostasis within the body by eliminating waste products and regulating fluid balance. Comprising organs such as the kidneys, ureters, bladder, and urethra, this intricate system filters metabolic byproducts, toxins, and excess substances from the bloodstream, ensuring their expulsion from the body in the form of urine. Additionally, the excretory system helps regulate blood pressure, electrolyte levels, and pH balance, thus safeguarding the internal environment's stability. Through its efficient filtration and elimination processes, the excretory system contributes significantly to overall health and bodily function.
