Urea is less toxic than ammonia.
The three main nitrogenous wastes are ammonia, uric acid and urea.
The Kidneys are a pair of organs with several functions. They are part of the urinary system, they maintain acid base balance and regulation of blood pressure. They excrete wastes such as ammonium are reabsorb water, glucose and amino acids. They also produce hormones
Firstly there is more than one metabolic reaction, the term simply means pathways of reaction that build up and/or breakdown complex molecules. So all cells have many metabolic pathways each with many reactions and many waste products. For this reason the question is unanswerable.
Vertebrates have the same waste-disposal problems as invertebrates. They must deal with the very toxic ammonia their bodies produce, and most vertebrates must expel wastes while conserving water.
The proteins are broken down in the stomach into simpler amino acids which when go into the liver are transformed into ammonia which is hazardous to body so the body further breaks it down into Urea, which is excreted out of the body through urine.
Urine is the bodies method of excreting excesswater and dissolved wastes.

The organs that are involved in the excretion of the digestive wastes are lungs, kidneys and the sweat glands in the skin. Hope this helped.
liver
Contractile Vacuole is the organelle responsible for excreting and collecting cellular waste.

Common nitrogenous wastes in urine are: urea, uric acid and ammonia.
The advantages of wastes segregation,it is easily to collect by the wastes collectors and you will know what to do in each wastes that you have been collected
Lysosomes are like the "garbage collectors" in a cell. They collect all of the wastes that the cell does not use and they get rid of them, either by excreting them or breaking them down.
