Morphological Description and Histological Structure of kidney in passer domesticus

Abstract

The result of the present study showed that the anatomical side in kidney of house sparrow consists of three lobes represented by cranial , middle and caudal lobes . Result of the present study showed that ureter in house sparrow extended at the uentral mid of the middle lope to the end of caudal lobe and appended in colaca ureter extends interiorly in cranial lobe of kidney . The results of the histological study revealed that kidney in house sparrow is differentiated into cortex and medulla . Cortex tissue in house sparrow contains different number of nephrons , each consist of glomerulus , proximal convoluted tubule (PCT) and distal convoluted tubule ( DCT) . The glomeruli distributed randomly within the kidney tissue but they are concentrated clrarly at the rentral surface of kidney . The medulla of house sparrow kidney appears with section of collecting tubule .Results of the histological study in house sparrow showed that the renal tubule lining by single layer of epithelial cells with brush border at its free surface within the (PCT) , while the free surface of (DCT) lack of the brush border .The results of histological showed that they are thin and thick segment of Henle loop .
