the answer is simply excretion
The process that removes metabolic waste from an organism is called the excretory process. Through this process excretes are substances that are not used by the organism and thus must be excreted.
Excretion is the process of removing metabolic waste products from an organism, primarily involving the kidneys, liver, lungs, skin, and large intestine. This process is essential for maintaining homeostasis and preventing the accumulation of toxic substances in the body. Without effective excretion, organisms would struggle to survive due to the build-up of harmful waste materials.
