Ureotelism is a biological process in which organisms excrete excess nitrogen primarily in the form of urea, a less toxic compound compared to ammonia. This adaptation is particularly beneficial for terrestrial animals, including mammals, as it allows for efficient nitrogen waste management with minimal water loss.
The excretory system is responsible for removing waste products and maintaining homeostasis by regulating the body's fluid balance, electrolyte levels, and pH. It primarily involves organs like the kidneys, liver, lungs, and skin, each playing a crucial role in filtering and eliminating different types of waste from the body.
