(1) renal arteries
(2) fetal inferior vena cava
(3) hepatic portal vein
(4) pulmonary arteries
(5) abdominal aorta
(6) superior mesenteric artery
(2) fetal inferior vena cava
(3) hepatic portal vein
(4) pulmonary arteries
Explanation:
- fetal inferior vena cava: Fetal inferior vena cava is the vein but is carries oxygenated blood
- hepatic portal vein: Hepatic portal vein carries deoxygnated blood but nutrient rich as it drains the blood from the intestine to the liver.
- pulmonary arteries: pulmonary arteries arise from the right ventricle and it carries deoxygenated blood from the right ventricle to the lungs for oxygenation.
