Verified step by step guidance

Begin by understanding the role of each vessel in the nephron's blood supply. The renal artery is responsible for delivering oxygenated blood to the kidneys.

Identify the first vessel in the correct sequence: the afferent arteriole. This vessel carries blood from the renal artery to the glomerulus.

Next, recognize the glomerulus as the site of filtration. Blood enters the glomerulus from the afferent arteriole, where filtration of blood occurs.

After filtration, blood exits the glomerulus through the efferent arteriole. This vessel is smaller in diameter than the afferent arteriole, which helps maintain pressure for filtration.

Finally, the blood flows into the peritubular capillaries. These capillaries surround the nephron tubules and are involved in the reabsorption and secretion processes, completing the path of blood flow through the nephron.
