Urogenital System Of Vertebrates Quiz Test Questions and Answers

Let’s start the quiz

The metabolic reaction occurring in animal body produces certain nitrogen containing material as ammonia, urea, uric acid etc. These materials are toxic to the body so they must be removed. This elimination of nitrogenous waste products from the animal body to regulate the composition of the body fluids and tissues is called excretion. The excretory system in vertebrates is closely associated with parts of reproductive system, particularly in males, so excretory and reproductive system together form Urogenital system All parts of the excretory system except for a few structure s near the terminal duct opening are mesodermal in origin. So, take this quiz and increase your knowledge about the urogenital system of vertebrates.
