What this chapter is about
All living organisms produce metabolic waste products as byproducts of cellular respiration and biochemical reactions. These waste products—including carbon dioxide, water, urea, ammonia, and uric acid—must be continuously eliminated to prevent toxic accumulation and maintain homeostasis. The process of eliminating these waste products is called excretion.
Animals accumulate various excretory products through metabolic activities or dietary excess, including:
