They excrete toxic substances.

Definition of ureotelic organisms. Terrestrial animals cannot use water freely for excretion because of less availability in the environment so ammonia is converted into a less toxic and easily soluble product urea. Among amphibians reptiles and other vertebrates patterns of nitrogen excretion appear generally related more to habitat than to phylogeny. Ammonia urea and uric acid are the main nitrogenous waste product in different animals.

Urea is less toxic and needs less water in comparison to Ammonia. Organisms which excrete excess Nitrogen from the body as urea are ureotelic. Excrete Nitrogen as URIC ACID Uric Acid is relatively insoluble in aqueous medium thus is excreted as semisolid crystals.

The major role of excretory system is the elimination of nitrogenous wastes. Ureotelic organisms include cartilaginous fish few bony fishes adult amphibians and mammals including humans. Unlike ammonia and urea uric acid is insoluble in water.

The excreta of uricotelic organisms is typically white. The animals which excrete excess nitrogen as solid or semi-solid uric acid are called urecotelic organisms. Medical Definition of uricotelic.

Excreting uric acid as the chief component of nitrogenous waste. Uricotelic organisms excrete uric acid as nitrogenous waste. These animals are called ureotelic.

Uricotelic This is a water conservation adaption usually for Arthropoda and more concisely for Insects An uricotelic organism excretes uric acid or its salts as a result of deamination. Birds conserve water for low weight Reptiles Ureotelic organisms. And those that excrete uric acid uricotelic.

Excreting nitrogen mostly in the form of uric acid birds are typical uricotelic animals. Two nitrogen atoms are eliminated through it and less water is needed for its excretion. Human beings are ureotelic.

Animals that excrete excess nitrogen in the form of urea are ureotelic. It predominantly occurs in reptiles birds and insects. Ureotelic organisms include cartilaginous fish few bony fishes adult amphibians and mammals including humans.

In animals nitrogenous excretion is grouped into three categories based on the form in which nitrogenous wastes are removed. All content on this website including dictionary thesaurus literature geography and other reference data is for informational purposes only. The species that excrete uric acid waste are called uricotelic organisms.

Prolonged dehydration leads to accumulation of nitrogen waste which causes death if not removed or diluted. Yurĭ-kō-tĕl ĭk New Word List. Ureotelic definition is - excreting nitrogen mostly in the form of urea.

How to use ureotelic in a sentence. The urea cycle also known as the ornithine cycle is a cycle of biochemical reactions that produces urea NH 2 2 CO from ammonia NH 3. Land animals mainly amphibians and mammals convert ammonia into urea a process which occurs in the liver and kidney.

The excretion of urea is called ureotelism. Their excretion requires less water as uric acid is the least toxic. Elasmobranchii adult Amphibia and Mammalia.

Urea is less toxic and less soluble in water than ammonia. UreotelicApplied to organisms that excrete in the form of ureanitrogenous waste derived from amino-acidcatabolism eg. Excrete Nitrogen as UREA.

Excretion in our body occurs through skin kidneys and lungs. Those that excrete urea ureotelic. This cycle occurs in ureotelic organisms.

Organisms that primarily excrete ammonia are called ammonotelic. Urea is a less toxic compound than ammonia. Among the three major forms of excretion of nitrogenous waste in organisms uric acid is the least toxic and the least soluble in water.

A Dictionary of Zoology. Ureotelic animals include Ascaris earthworm both are ammonotelic and ureotelic cartilaginous fishes like sharks and sting rays semi-aquatic amphibians such as frogs and toads aquatic or semi aquatic reptiles like turtles terrapins and alligators and man and all other mammals. A ureotelic organism excretes excess nitrogen as urea.
