Osmoregulation and excretion copyright © 2005 pearson education, inc publishing as benjamin cummings • overview: a balancing act • the physiological systems of animals - operate in a fluid environment • the relative concentrations of water and solutes. Excretion the process, by which waste product of metabolism from the system of an organism are eliminated from the body organs of the excretory system lungs - removal of excess carbon dioxide liver osmoregulation is achieved by the contractile vacuole.
Excretion is the process by which metabolic waste is eliminated from an organism in vertebrates this is primarily carried out by the lungs, kidneys and skin this is in contrast with secretion osmoregulation respiration (physiology) urination.
