Question

In details outline Renal Circulation (That is blood circulation inside the kidney)

Answer 1

The renal artery provides the blood flow to the kidney, branch from abdominal aorta forms the right and left renal artery, Just before reaching the kidney, each renal artery divides into five segmental arteries, which provide blood to the various regions of the kidney, this further divides into interlobar artey which penetrate the renal capsule and extend through the renal columns between the renal pyramids. At the junction between the renal cortex and renal medulla, the interlobar arteries form the arcuate arteries, which turn to follow the contours of the renal pyramids. From the arcuate arteries several branches, known as interlobular arteries, separate at right angles and extend through the renal cortex toward the exterior of the kidney. Each interlobular artery forms several afferent arterioles, the afferent arteriole than supply the glomerulus, from the glomerulus effernt arterioles form the peritubular capillary and vasa recta, all the veins than converge, until reaching renal vein

Summary : abdominal aorta --> renal artery --> segmented artery --> interlobar artery --> arcuate artery ---> cortical radiate artery -->afferent arteriole --> glomerulus -->efferent arteriole --> peritubular capillary --> vasa recta --->venules --> renal vein.
