Answer:
VEIN (venous return)
Explanation:
The venous return to the heart is rich in C02 and waste
The waste and C02 in blood is transported to the kidney and the liver in the Veins and leaves through the(<u> right and left renal veins and portal vein </u>respectively) via the inferior vena cava; to the heart for oxygenation
The C02 rich blood (deoxygenated blood) with the waste removed in the kidney and liver is transported by the vena cava → the right atrium→ right ventricle → pulmonary vein for pulmonary circulation in the lungs to release the C02 and take Oxygen(oxygenated blood) back to the heart ,which is pumped by the left ventricle into the Aorta ( artery) and other arteries in systemic circulation.
Thus Veins transport deoxygenated( with C02) blood and wastes
Arteries transport Oxygenated blood ( with Oxygen) and metabolites
