Introduction to Human Excretory System

The human excretory system is a system that functions to remove unnecessary or harmful waste substances from the body's metabolism, thus helping to maintain the balance of body fluids and eliminate toxic substances. This system consists of several organs that work together to remove these residual substances in the form of urine, sweat, carbon dioxide, and others, so that the body can function normally and healthily.
