Ureoteliset

Ureoteliset, also known as ureotelic animals, are a group of organisms that excrete nitrogenous waste in the form of urea. This process is facilitated by the enzyme urease, which converts ammonia into urea in the liver. Urea is then transported to the kidneys, where it is excreted in the urine. This method of nitrogen excretion is more efficient than the ammonotelic method, as it reduces the risk of ammonia toxicity in the body. Ureotelic animals include many mammals, birds, and reptiles. The ureotelic system is advantageous in environments where water is scarce, as it allows for the conservation of water by reducing the amount of water lost in urine. However, it also requires a higher metabolic cost due to the energy-intensive process of urea synthesis. The ureotelic system is a key adaptation that has allowed these animals to thrive in a variety of environments.
