COMPARATIVE ANATOMY: EXCRETORY SYSTEM OF FROG AND FISH

Kidneys are the major excretory organs in all vertebrates. Some other organs such as lungs, gills, liver, intestine and skin also remove certain waste materials besides their normal functions. These are also known as the accessory excretory organs. Both shark and frog are anamniotic animals.   The kidneys lie dorsal…
