Thorax - transverse section

You selected: left atrium

The left atrium receives newly oxygenated blood. The right and left pulmonary veins return blood from the lungs. These veins are the only ones that carry oxygenated blood. Ateries always carry blood Away from the heart while veins return blood to the heart.

The left atrium then pumps the oxygenated blood into the left ventricle where it will be pumped to the rest of the body. The mitral value regulates the flow of blood between the two chambers.
