      The present study was conducted to focusing the light on the anatomical and histological picture of the kidney of the rabbit, for this purpose the report recorded that the anatomical findings which was the kidney large relatively firm, retroperitoneal, reddish brown in color and unilobular with bean-shaped surrounded by a tough fibrous capsule with abundant amount of per-renal fat tissue. The right kidney was between the 11^th and 12^th intercostal space and the second lumbar vertebrae while left kidney localized between the 2^nd and 4^th lumbar vertebrae.

   The right and the left renal arteries supply kidneys of the rabbit that originated from the related side of the abdominal aorta, they were entering the hilus of the kidney.

   Histologically were reported that the kidney of rabbit surrounded by a thin fibrous capsule and consists of darker, granular and highly vascular outer cortex which had the renal corpuscles and inner medulla which was slightly thick and less vascular that had the tubules of the nephrons .

   The functional unit of the kidney called nephron and each nephron consists of renal corpuscle, proximal convoluted tubule, loop of Helene, distal convoluted tubule, collecting tubule and collecting duct.

   The sections extend from the capsule to the medulla showing variations in distribution of renal corpuscles, otherwise the straight tubules of the nephrons and the collecting ducts continue from the cortex into the medulla.
