pulmonary veins
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
Blood entering the left atrium is oxygenated blood coming from the lungs that is pumped throughout the rest of the body.
Four main blood vessels enter/exit the heart: two veins and two arteries. Oxygenated blood enters the left ventricle through the pulmonary vein. This same blood is then pumped out of the left atrium via the aorta. Meanwhile, de-oxygenated blood enters the heart in the vena cava; before leaving through the pulmonary artery.
Two, the left and right pulmonary veins.
pulmonary vein
The right and left pairs of pulmonary veins.
left ventricle Blood enters the left & right atria. Blood entering the left ventricle came from the left atrium. Blood from the body enters the right atrium. From there it is pumped to the right ventricle, through the lungs, to the left atrium, to the left ventricle, then throughout the body. Then back to the right atrium...

The blood enters through the superior and inferior vena cava.
Two pulmonary veins from the right lung and two pulmonary veins from the left lung.
Are you doing a project or something? Anyway...The right and left atria receive the blood entering the heart.
