And these common iliac arteries deliver oxygenated and nutrient filled blood to the leg portion of our body, to our right and our left leg. So these are some of the major arteries that are found within our arterial circulation system. Now of course we have many more arteries that we haven't actually shown. For example, we have our pulmonary arteries. So our right ventricle, when it actually contracts, it forces all that deoxygenated blood into the pulmonary trunk. And the pulmonary trunk, this section here extends into our left and our right pulmonary artery.
