The renal corpuscle is composed of a glomerular capillary (C) tuft  and a double-walled renal capsule.

The renal capsule has two parts: a parietal layer lined by a simple squamous epithelium (BC) and a visceral layer formed by podocytes (black arrows). 

The urinary space (asterisks) is between the two layers of renal corpuscle.

An arteriole (A) is observed in the vascular pole.

The proximal convoluted tubules (PCT) have obvious brush border (triangles).

The distal  convoluted tubules (DCT) has fewer and less well developed microvilli than PCT does and its lumen is more cleaner. 

The proximal straight tubules (PST) also have obvious brush border (triangles), whereas

The distal  straight tubules (DST) has fewer and less well developed microvilli than PST does and its lumen is more cleaner. Besides, their nuclei are located in the apical portion of the cells. 

 In the medulla, the thin segment (T) formed by a low cuboidal or simple squamous epithelium could be observed.

The photography shows parts of the renal corpuscle, including glomerular capillaries (C) and a renal capsule.

The renal capsule has two parts: a parietal layer lined by a simple squamous epithelium (BC) and a visceral layer formed by podocytes (black arrows). 

Podocytes (black arrows) extend their processes around the glomerular capillaries (C)

The endothelium of the glomerular capillary has numerus fenestrations (arrow heads).

Podocytes (black arrows) extend their processes on the  glomerular basement membrane of the glomerular capillaries (C).

The most prominent feature of proximal convoluted tubules  is the closely packed microvilli (Mv) on the apical surface of cells.

The apical surface of proximal tubule cell shows  closely packed microvilli (Mv). Vesicles (V), lysosomes (L) and mitochondria (M) are present in the cell.

Many longitudinally oriented mitochondria (M) are located in the basal striation of proximal tubule cell.

Closely packed microvilli (Mv) are obvious in the apical surface of proximal tubule cell.

The apical surface of distal convoluted tubule cell  has relatively short and less-developed microvilli (Mv).

Many longitudinally oriented mitochondria (M) are located in the basal striation of distal tubule cell.

Many longitudinally oriented mitochondria (M) are located in the basal striation of distal tubule cell.

The apical surface of distal convoluted tubule cell  has relatively short and less-developed microvilli (Mv).

The urinary bladder is lined by the transitional epithelium (Epi) which character is that cells of the surface layer exhibit  dome-shaped.

The connective tissue (CT) containing blood vessels is under the epithelium and the muscularis layer (M) is  beneath the CT. 

The cell membrane of transitional epithelium contains the unique plaques (arrows)  which may invaginate into cell to be fusiform vesicles (arrow heads).

The cell membrane of transitional epithelium contains the unique plaques (arrows)  which may invaginate into cell to be fusiform vesicles (arrow heads).  

The membrane of fusiform vesicles appears to be similar to the cell membrane of the transitional epithelia cell.
