answer:No, it’s through the injection into the inferior or superior vena cava, to the right atrium, then the mitral valve, then to the right ventricle. After that it goes through the pulmonic valve into the pulmonary artery to the lungs. Then back to the heart it goes to the left atrium, tricuspid valve, and left ventricle. Finally, out through the aortic valve into the aorta. If you want a more direct route, put a pointed stick through the chest wall on the left side and push smartly through the flesh. That may irritate the recipient for a moment before he collapses, though. The stomach is a very inefficient way to get to the heart as there are several layers of tissue between the stomach and the heart. I mean, there is the stomach wall, the fascia, the diaphragm, the pericardium, and then finally the myocardium.
