Two pulmonary veins empty blood into the left atrium.
Deoxygenated blood enters the right atrium, then the right ventricle which pumps the blood to the lungs where it is oxygenated. The two pulmonary veins then take the newly oxygenated blood back to the heart through the left atrium and into the left ventricle which then pumps the oxygenated blood around the rest of the body.
The atrium does not carry gas. Blood flows through it. The blood in the left atrium is oxygenated.

Blood entering the right atrium is deoxygenated and saturated with CO2. Blood that is entering the left atrium has passed through the lungs and is oxygenated. It returns to the left atrium via the pulmonary vein and is saturated with oxygen. - Med Student
the left atrium...it pumps blood thereThe pulmonary vein carries oxygenated blood from the lungs to the left atrium of the heart.
The pulmonary trunk and its branches receive blood from the right ventricle, which then carries deoxygenated blood to the lungs for oxygenation.
Heart (Left Ventricle) -> Arteries -> Arterioles -> Capillaries -> Venules -> Veins -> Heart (Right Atrium)
There are four pulmonary veins and are large blood vessels that receive oxygenated blood from the lungs and drain into the left atrium of the heart.

The left atrium of the heart receives oxygented blood from the pulmonary veins returning oxygenated blood to the heart.
