MICROANATOMY

Detailed explanation-1: -Blood flows into your kidney through the renal artery. This large blood vessel branches into smaller and smaller blood vessels until the blood reaches the nephrons. In the nephron, your blood is filtered by the tiny blood vessels of the glomeruli and then flows out of your kidney through the renal vein.

Detailed explanation-2: -The blood travels from the aorta in the heart to the renal arteries in each of the kidneys. The renal artery branches into smaller arteries called the afferent arterioles. The blood travels from the afferent arterioles to the glomerulus, located in the nephron.
