The process of regulating water content and ion concentration in the body of an organism is called Osmoregulation.
Osmoregulation is related to the habitat of an organism. In human beings this function is performed by the kidneys.
Egestion – The process involves removing undigested waste food products from the body of the organism.
Excretion – The process involves removing wastes from the cells of organisms.
The biological process of removal of excess or toxic waste products of metabolism from the body of an organism is called Excretion.

Dialysis is an artificial process used to remove water and waste substances from the blood when the kidneys fail to function properly.
Dialysis works on the principles of the diffusion of solutes and ultrafiltration of fluid across a semipermeable membrane.
Why Is Dialysis (Haemodialysis) Necessary?
The total amount of Urine Produced is regulated by:
The total amount of Nitrogenous waste Produced.
Fecal matter is not produced by metabolism, removal of feces cannot be considered as excretion.
Why is the Removal of Faeces from the Alimentary Canal not considered to be Excretion Read More
