Some organs secrete the metabolic system in the human body, which can be called excretion. These organs involve the skin, lungs, kidneys, and liver.
As its function as excretion, human skin can excrete residual sweat substances. There are 3 layers of skin, epidermis, dermis, and subcutaneous which have functioned as a protective layer of the body.
Along with their function as excretion, the lungs also excrete waste products of metabolism that are not needed by the body. The lungs expel gases from the respiratory process, namely carbon dioxide and water vapor.
