Urinary system
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.
The wastes which are collected in the kidney is the toxic nitrogenous waste urea, excess water and excess salts are the main wastes.
Embryos do not excrete nitrogenous wastes into the environment but rather rely on the mother's body to remove these wastes through the placenta. The mother's kidneys process the nitrogenous wastes from the embryo's blood and excrete them into her own bloodstream for elimination.
The urinary system excretes nitrogenous wastes. The lungs excrete carbon dioxide.
Common nitrogenous wastes in urine are: urea, uric acid and ammonia.
nitrogenous wastes
The two main wastes removed by the urinary system from the blood are urea and creatinine. Urea is a byproduct of protein metabolism, while creatinine is a waste product of muscle metabolism.
Urea is the less toxic in nature among the nitrogenous wastes where as Ammonia is 100,000 times toxic than urea.
Your kidneys filer your blood of nitrogenous wastes. These wastes are then moved to the bladder in the form of urine and expelled.
Kidneys filter nitrogenous waste from the blood.
