Excretion


Excretion is a process that occurs in organisms capable of eliminating those products that it no longer needs for its normal functioning, it is a function of living beings, such as humans and animals, which is why it is said to be a physiological process. .

Substances eliminated through the excretion process are toxic to the body, they are not eliminated within our body, but the body through various processes expels them out of it, these products that are expelled from our body are known as waste metabolic, in which we can place urine and feces as an example, although there are also other types of substances such as sweat, which is directly released by glands that are everywhere in our largest organ, the skin.

One of these toxic substances is ammonia, which originates in some part of our body and is created from the decomposition of proteins that have been inside each cell for a long time, that is, old proteins, and since ammonia is a poison For the body, it is responsible for eliminating it so that it can continue to function in the best possible way. In addition to ammonia, excess nitrogen and carbon dioxide are also excreted, among others, which are mostly originated from the foods that we ingest All this work is done by our body through the so-called excretory system, which is made up of the liver, the urinary system and the sweat glands.
