• Heart → Capillaries → Arterioles → Arteries → Veins → Heart.

Answer 1

Heart → Aorta → Arteries → Arterioles → Capillaries → Veins → Heart.

Arteries transport oxygenated blood and divide and re-divide into capillaries as needed. Capillaries join together to form veins, which transport deoxygenated blood to the heart.
