Detailed explanation-1: -The excretory system of the vertebrate body includes the kidneys, the skin, gills and/or lungs, and specialized salt-excreting or salt-absorbing structures.
Detailed explanation-2: -The renal excretion of nitrogenous compounds plays an important role not only in the elimination of nitrogen end-products but also in regulating the acid-base and osmotic balance of body fluids. The major nitrogenous compounds excreted by the vertebrate kidney are ammonia, urea and uric acid.
Detailed explanation-3: -THE URINARY SYSTEM IN VERTEBRATES The urinary organ system lies in the abdominal region and consists of paired kidneys which are the principal organs of excretion and osmoregulation. These kidneys lie dorsal to the coelom, (retroperitoneal), one on each side of the dorsal aorta.
