黑天鹅肾脏组织形态结构OACSTPCD

The research aims to study the renal histology and morphology of black swan by gross anatomy and HE staining.The kideny is composed of two parts:the envelope and the parenchyma.The envelope is a thin layer of dense connective tissue.The kidney of black swan was surrounded by several developed renal lobules,which made the kidney surface uneven.The renal tubules were radially distributed in the central vein of the lobule,Medulla and cortex from inside to outside.Renal corpuscle could be divided into two kinds.One kind belonged to renal corpuscle type Ⅰ,which characterized by simple squamous epithelium lining of the renal capsule,and the same to small mammals renal lining.The other kind was renal corpuscle type Ⅱ which was single low cuboidal epithelium,cuboidal epithelium or low columnar epithelium lining.There was a brush border on the free surface of cuboidal epithelium or low columnar epithelial.There were abundant vascular distributions in the parenchyma.The great central vein in the deep renal parenchyma ran parallel with the ureter branch.
