Excretory system


The excretory system is the system of an organism's body that performs the function of excretion, the bodily process of discharging wastes. It is responsible for the elimination of wastes produced by homeostasis. There are several parts of the body that are responsible for this process, such as the sweat glands, the liver, the lungs, and the kidney system. It removes wastes of the organism, balancing and regulating the chemical composition of its body fluids. The excretory system eliminates excretory products from the body, collects water and filters body fluids. Its parts include anything that aids in depleting wastes and unneeded substances. Without the excretory system, the build-up of harmful wastes could damage the body, resulting in destructive, dangerous, and even fatal consequences.
