Excretion
Gbogbo ọrọ náà
Every metabolic reaction in your body produces something useful, but many also generate waste that would become toxic if it were allowed to accumulate. Excretion is the process that removes these metabolic waste products and keeps your internal chemistry within safe limits.
This topic covers how carbon dioxide and oxygen arise as waste products of metabolism in plants and how they leave through stomata, as well as the roles of the lungs, kidneys and skin as excretory organs in humans.
