It flows through the pulmonary vein toward the heart.
The pulmonary vein enters the left atrium of the heart.
The lungs, I the alviolies.

The lungs.
Actually it is the Left Atrium
Deoxygenated blood goes to the lungs to get rid of carbon dioxide and to pick up oxygen.
It is not just one blood vessel that goes and come back from the lungs. Vessels that leave the heart are known as arterieswhile those that enters the heart are known as veins. The blood leaves the heart via the pulmonary trunk which terminates into 2 pulmonary arteries, one for each lung. The blood then leaves the lungs and enter the heart through 4 pulmonary veins, (all opening into the left atrium), of which each two are from one lung.
When blood leaves the lungs through the pulmonary veins, it returns to the heart and enters the left ventricle.
maybe your question goes this way..."how does oxygen enter the blood from the lungs?"Two types of blood vessels carry blood throughout our bodies: The arteries carry oxygenated blood (blood that has received oxygen from the lungs) from the heart to the rest of the body. The blood then travels through the veins back to the heart and lungs, where it receives more oxygen.
The place is the same for both; the alveoli in the lungs.
to the heart to be pumped out to the body through arteries
Right ventricle to the lungs Left ventricle to the body
