Major anatomical changes in vertebrates kidneys separate those of birds and mammals from kidneys of lower vertebrates. General increase in animal size from fish to mammals is reflected by an increase in total number of nephrons per kidney, rather than by constant change in tubular dimensions.[well established][VHOG] excretory system
