We've learned that oxygenated blood goes comes into the heart at the left atrium which is part of the heart, and then goes to the left ventricle which pushes the blood to all the parts of your body.
The big tube that the left ventricle pushes the blood to first is called the aorta.
The aorta is a big long tube that goes up from your heart, then turns and goes downward all the way down to your hips area.
