Urea plays a crucial role in maintaining homeostasis by aiding in the excretion of excess nitrogen, a byproduct of protein metabolism. Produced in the liver through the urea cycle, it is transported to the kidneys, where it is filtered out of the blood and excreted in urine. This process helps regulate blood urea nitrogen levels and prevents toxic accumulation, contributing to the overall balance of fluids and electrolytes in the body. By managing nitrogen waste, urea is essential for maintaining the internal environment necessary for cellular functions.
