This video tutorial explains the blood supply to the kidneys, detailing the pathway from the heart through the aorta to the renal arteries, and further into the kidneys via segmental, interlobar, and arcuate arteries. It covers the role of nephrons in filtration, describing the afferent and efferent arterioles and the glomerulus. The video concludes with the venous return of blood from the kidneys to the heart, highlighting the renal veins and inferior vena cava.
