an illustration of a human heart. The aorta, emerging from the top of the heart, is enlarged by an unruptured, but very swollen aneurysm. the aorta (only) is wrapped around the outside, many times, with beautiful vines and flowers. the vines and flowers struggle to reinforce the aorta, to keep it from rupturing. the aorta strains against the binds that hold it together. there are no vines or flowers on the rest of the heart.
