What is the significance of excretion processes in living organisms?

Isolation plays one of the key roles in the life of any living organism. During the excretion processes, toxic substances are released from the cells, which are formed during the cleavage of nucleic acids, amino acids and other compounds (for example, uric acid and urea, ammonia). Carbon dioxide, excess water, water vapor, etc. are also removed from the body.
In the process of excretion, not only toxic and toxic substances are removed from the body, but excretion processes are involved, for example, in the thermoregulation of the body (sweating).
