EXCRETORY SYSTEM Urologist’s: Dr. Nestor, Dr. David, Dr. Gabriel
The excretory system is a biological system that removes excess, unnecessary or dangerous materials from an organism. It is responsible for the elimination of oxygen waste products of metabolism as well as other nitrogeneous materials. Since the normal operation of most biological systems creates waste, the excretory system is not necessarily distinct from other systems. Instead, it often represents the various excretory processes of several different systems.
The main organs of the excretory system are the kidneys, the ureters, the urinary bladder and the urethra.
