ANATOMICAL AND HISTOLOGICAL INVISTGATION OF THE KIDNEY IN GOAT (Capra hircus)

Abstract

Thirty specimens of kidney (15 left and 15 right) from healthy adult goat were used in this study to show the morphology, the vascular architecture and histological structure of the kidney in the goat. The kidneys of goat were fixed in sub lumber region by large amount of peri renal fat as a cushion surrounding the kidneys. The right kidney placed slightly anterior to the left kidney both are bean shape, there is no significant difference in weight of two kidneys. Corrosive resin cast technique was used to investigate the blood supply and collecting system of the urine, the collecting system in the kidneys of goat was formed from several collecting tubules. Each collecting tubule opening into a larger ducts, a papillary duct, close to the apex. The papillary ducts drain into the about 10-12 renal recesses, there was no calyces. The microscopical examination revealed a thin capsule surrounded kidney, the parietal layer of bowman capsule was simple squamous epithelium, resting on well-developed basement membrane. Well-developed juxtaglomerular apparatus. The luminal surface of the cells of proximal convoluted tubules have brush border which were positive with PAS stain. The henel loop was long. That mean the kidney of goats is maintaining to the water and need for more reabsorption of water.
