Uberon definition : The renal system in an anatomical system that maintains fluid balance and contributes
to electrolyte balance, acid/base balance, and disposal of nitrogenous waste products..;
Uberon synonym : systema urinaria; urinary system; excretory system; systema urinarium; urinary tract;
Uberon related term : renal/urinary system; renal or urinary system;
Uberon Homology note : Evolution of vertebrate renal anatomy appears quite conservative when compared, for
example, to evolution of respiratory and cardiovascular systems in vertebrates. 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];
Uberon Taxon note : This definition is inclusive of the organs of the vertebrate renal system, as well
as the Malpighian tubules of insects, and allows for future incorporation of structures
such as the antennal glands of crustaceans;
