There are no noticeable difference in fetal elimination of nitrogenous wastes which would account for the structural differences between pigs and humans. Waste is eliminated through urination.
Embryos excretes nitrogenous wastes into the placenta.
Urine contains nitrogenous wastes.
the kidney is referred to as an excretory organ and excretes urea, which is a less toxic form of uric acid.
Urinary system
The plants wastes are eliminated in a very simple way. They are normally removed from the system of the plants through the stomata. This is in the same way that CO2 enters into the plants.
The urine is composed of 95% water, and 5% solutes. The solutes are comprised of nitrogenous wastes such as urea, uric acid and creatine. There are also trace amounts of electrolytes and hormones.
Common nitrogenous wastes in urine are: urea, uric acid and ammonia.
Urea is the less toxic in nature among the nitrogenous wastes where as Ammonia is 100,000 times toxic than urea.
