oxygenated blood is carried by arteries and not veins. when unoxygenated blood pass through the heart, it is brought by either the superior vena cava or the inferior vena cava.
There is the pulmonary vein.
It is a vein that carries blood from the lower body to the heart, also known as the posterior vena cava.
Pulmonary vein carries more oxygen because it is an exceptional which carries oxygenated blood
The pulmonary vein carries oxygen-rich blood from the lungs to the heart.
Veins and arteries are not classified by whether they carry oxygen-rich or oxygen-poor blood. They are classified according to whether they carry blood to the heart or away from the heart. Veins carry blood to the heart and arteries carry blood away from the heart. So the pulmonary vein carries blood to the heart, which is why it is a vein. Also, the pulmonary artery, which carries oxygen-poor blood to the lungs is an artery because it carries blood away from the heart.
Artery - always carries blood FROM the heart Vein - always carries blood TO the heart The vein which brings blood to the heart from the lungs is the PULMONARY VEIN ('pulmonary' = lungs). The one carrying blood away from the heart to the lungs is the pulmonary artery. Easy.
pulmonary vein
The popliteal vein carries blood from the knee to the thigh and calf muscles and ultimately to the heart. The vein is formed from the merging of the two posterior tibial veins and ends as it merges in to the femoral vein.
The vein that carries more oxygen than carbon dioxide is called the pulmonary vein. This vein transports oxygenated blood from the lungs to the heart, specifically from the pulmonary capillaries to the left atrium. In contrast to systemic veins, which carry deoxygenated blood, the pulmonary vein is unique in its role of delivering oxygen-rich blood to the heart for distribution throughout the body.
The pulmonary vein carries blood with the highest oxygen concentration, as it transports oxygen-rich blood from the lungs to the heart. This freshly oxygenated blood is then pumped out to the rest of the body by the heart.
The only vein that normally carries oxygen rich blood is the pulmonary vein which carries freshly oxygenated blood from the lungs back to the heart for distribution to the body. Ordinary veins can have oxygen poor blood but don't carry oxygen rich blood.
