The renal artery divides and subdivides and eventually divides into very tiny blood vessels known as the African arterios. And these are the blood vessels that carry not only the oxygenated and the nutrient filled blood, but also the blood that contain the waste products that must be excreted. And it brings that blood to our nephron. So this is the apharynt arteriol shown here, and it connects with a network of capillaries known as araglomerilus. This is Arglomerilus, shown here. So the African arterio is the blood vessels that ultimately comes from the renal artery and it brings the oxygenated and the nutrient filled blood to our nephron.
