renal veins

Answer 1

The blood flow in the kidney followys this path -

Aorta --> Renal artery --> segmental artery --> interlobar artery --> arcuate arteries --> interlobular arteries --> cortical radiate arteries --> afferent arterioles --> glomerular capillaries --> efferent arterioles --> Vasa recta--> peritubular capillaries --> cortical radiate vein --> arcuate vein --> interlobar vein --> segmental vein --> renal vein --> inferior venacava.

Renal arteries arises from the abdominal aorta and supplies both right and left kidneys. Right renal artery is longer than left renal artery. Renal artery divides into segmental artery, there are three segmental arteries- superior segmental, anterior segmental and inferior segmental. These segmental arteries further divides into interlobular arteries which continue as smaller branches known as arcuate arteries. Afferent arterioles arise from cortical radiate branches of arcuate arteries and forms peritubular capillaries. Efferent arterioles arises from this peritubular capillaries and drains to cortical radiate vein which drains into arcuate vein and finally to interlobar vein. Many interlobar veins drain into respective segmental vein. Segmental vein drains into renal vein which ultimately drains blood to inferior venacava.
