Detailed explanation-1: -The right side of the heart i.e. the right atrium and right ventricle deals with deoxygenated blood.

Detailed explanation-2: -Thus the right side of the heart carries deoxygenated blood and the left side of the heart carries oxygenated blood.

Detailed explanation-3: -Deoxygenated blood from the lower half of the body enters the heart from the inferior vena cava while deoxygenated blood from the upper body is delivered to the heart via the superior vena cava. Both the superior vena cava and inferior vena cava empty blood into the right atrium.

Detailed explanation-4: -The right side pumps deoxygenated blood (low in oxygen and high in carbon dioxide) to the lungs. The left side pumps oxygenated blood (high in oxygen and low in carbon dioxide) to the organs of the body. Deoxygenated blood enters the right atrium from the vena cava.

Detailed explanation-5: -All the veins carry deoxygenated blood except the pulmonary vein. It carries oxygenated blood from lungs to the heart.
