The correct sequence of blood vessels associated with the nephron is afferent arteriole → glomerulus → efferent arteriole → peritubular capillary network → venule → renal vein. This is because the afferent arteriole brings blood into the glomerulus, where filtration occurs. The efferent arteriole then carries blood away from the glomerulus, and it branches into the peritubular capillaries, which surround the renal tubules and facilitate reabsorption and secretion. The peritubular capillaries then converge into venules, which ultimately drain into the renal vein.
