Basics of Renal Blood Supply and Flow

The video tutorial explains the blood supply to the kidneys, starting with the renal artery and its division into segmental and interlobar arteries. It covers the role of arcuate and cortical radiate arteries in supplying blood to nephrons. The glomerulus is highlighted as the site of filtration, with blood entering via afferent arterioles and exiting through efferent arterioles. The tutorial also discusses the vasa recta and peritubular capillaries, which supply different parts of the nephron, and their eventual convergence into the cortical radiate vein.

Explain the difference between interlobar arteries and arcuate arteries.
