-The kidneys of the bovine do not lose their foetal lobulation.  In fact the surface of each kidney is divided into approximately 12 lobules.    The right kidney is flattened and ellipsoidal where as the left kidney is thicker at the caudal end than the cranial.  Each kidney is surrounded by the capsula adiposa; a layer of fat.  Despite what it’s externally lobulated appearance may suggest the cortex of the bovine kidney is continuous and the kidney is of multipyramidal type.  The bovine kidney has no renal pelvis but rather the [[Ureters - Anatomy & Physiology | Ureters]] enters the kidney and divide into a cranial and caudal branch.  These branches then subdivide and the papilla at the apex of the pyramids open and drain into these.

 The right ureter leaves the kidney and passes along the roof of the abdomen to the pelvis in a fairly standard pattern.  The left ureter however moves across the dorsal surface of its kidney to return to the midline and follow a course as if the kidney was located on the left.  (both kidneys in the bovine are located on the right see the anatomical landmarks section for further details)

 ==Introduction==
 The kidneys are paired organs which reside in the dorsal abdomen.  One on the left and one on the right.  Their role is to filter the blood through the glomerulus to form what is known as the filtrate.  This filtrate is then on the whole reabsorbed along the nephron until what is left comprises compounds superfluous to the requirements of the organism.  Some compounds, normally fully reabsorbed, are on occasion present in the body in excess.  The kidney tubules are able to respond to this excess and excrete such compounds in greater amounts.  This is how the kidneys play a major role in the homeostasis of the organism.  The kidneys also plays a vital role in the total water balance of the organism.  Varying their excretion of water in relation to the hydration status of the animal.
