Renal Blood Flow - Kidney

About 25 % of one's total cardiac output goes to the kidneys to be filtered.

The summary of this flow is:
Aorta --> Renal artery --> interlobar artery --> arcuate artery --> interlobular artery --> afferent arteriole --> glomerular capillaries --> efferent arteriole -->
peritubular capillary plexus --> interlobular, arcuate, and interlobar veins

 
This photograph illustrates some of the larger vessels. 

At low power in a fetal kidney, the location of the arcuate vessels at the cortex/medulla border is evident. 
 

This vascular preparation shows afferent arterioles branching off an interlobular artery, then dividing into glomerular capillaries. 

The arterioles and glomerular capillaries will be discussed in greater detail later.

There are some other blood vessels present, like the stellate arteries found just beneath the capsule, and the vasa recta which nourish cells in the medulla.
