"low oxygenated blood/carbondioxide"
The above statement is not always true. For example, the pulmonary vein brings oxygenated blood from the lungs into the left atrium, while the pulmonary artery takes deoxygenated blood from the right ventricle to the lungs.
The answer is valves.
Veins need valves to prevent the backflow of blood, as venous pressure is not great enough to overcome forces (such as gravity) on its return to the heart.
However, when the heart pumps, enough pressure is provided to send the blood throughout the body, so arteries do not need valves.
