What passes into the atrium from the veins?

Left atrium of the heart.

Left atrium receives oxygenated blood from pulmonary veins which bring purified blood from lungs and passes the pure blood into left ventricle.

Four pulmonary veins, which are two from each lung, enter the left atrium of the heart. Oxygenated blood is contained in these veins that then drain into the left atrium.

The right and left pulmonary veins bring blood to the left atrium.

Atrium is the chamber if the heart receiving blood from the veins.

the pulmonary veins, the only veins to carry oxygenated blood empty into the left atrium.

After the blood leaves the pulmonary veins it goes to the left atrium then passes the bicuspid valve and enters the left ventricle where it is pumped to the aorta and the rest of the body. Pulmonary veins are the only veins that carry oxygenated blood.

Systemic veins carry deoxygenated blood from the body to the right atrium of the heart. Pulmonary veins carry oxygenated blood from the lungs to the left atrium of the heart.

the pulmonary veins send blood first to the left atrium, the blood passes through the mitral valve and then to the left ventricle

Veins carry blood toward the heart. The Superior and Inferior Vena Cava (unoxygenated blood) to the right atrium Pulmonary veins (oxygenated blood) to the left atrium

These are the last veins blood passes through on it's journey back to the heart they empty into the right atrium.

Yes, blood leaving the lungs via the pulmonary veins goes into the left atrium.

The human heart has 4 chambers, a left and a right atrium, and a left and a right ventricle. Circulation works in the following manner Veins merge into the vena cavas, which take deoxygenated blood into the right atrium of the heart. The right atrium passes blood into the right ventricle. The right ventricle pumps this blood into the pulmonary arteries, taking blood to the lungs to obtain oxygen. Blood is then cycled through the…

left atrium resieves oxygenated blood from pulmonary veins

The pulmonary veins are veins which carry oxygenated blood (unlike most veins) back from the lungs to the left atrium of the heart.
