Abstract
The present study was Carried out in karbala involved twenty adult male goat to know the histological structure on the kidney. The anatomy which had paired of kidney smooth enclosed by thin fibrous capsule. The histological structure of the kidney consist of two reigons cortex and medulla , the percentage of thicknesof medulla to cortex . The renal unit (Nephrons)consist of glomerulus and renal tubules.which had diameter mean (31.29±5.060) µm.The glomerulus was encapsulated by double Layers of epithelial cells called Bowmanscapsule , the first layer was external parietal layer while the second was internal Visceral layer.The glomerulus was linked by proximal convoluted tubule which lined by simple columnar epithelial tissue which has brush border from the free ending of cells, while the result showed disappeared the free surface of cuboidal cells which lined of distal convoluted tubule from the brush border .The medulla of kidney contains of longer loops called Henles Loop which had diameter mean (53.14±13.306) µm. The thick descending limb of the loop was lined by simple epithelial from squamous cells while the thick ascending limb of loop was lined by cuboidal lower cells.The medulla consist of collecting tubule which had diameter mean (14.67±2.309) µm and lined by from cuboidal cells to columnar cells with littel level of cytoplasm in their cells.
