Left side of the heart

After the blood goes into the lungs it goes back to the left side of the heart. It enters through the pulmonary veins to the left atrium, then to the left ventricle them out of the aorta and inferior vena cava. (Oxygenated blood.) After it travels out the aorta to the top part of the body and gets deoxygenated. After it leaves the aorta it goes to the whole body.
