Anatomically, this region of the duodenum is the portion of the duodenal flexure.
This imаge shоws the epithelium thаt fоrms the nephrоn. Specificаlly, this epithelium would be found in the tubule. This region of the tubule is the region of the nephron to receive the plasma that is filtered out of the glomerulus and collected by the Bowman’s capsule. Blood that enters the capillary of the glomerulus will enter via the arteriole, and exit the glomerulus via the arteriole thanks to the function of a unique cell that wraps around the glomerular capillary. These unique cells are called and ensure that the blood pressure in the exiting arteriole is high enough to push the remaining blood into the next capillary. If this were a cortical nephron, which comprises the of the nephrons of the human kidney, this second capillary could be called a .
