you take me everywhere, starting from my inferior and superior vena cava, to my right atrium, through my tricuspid valve that leads to my right ventricle, through my pulmonary semi lunar valve, to the pulmonary trunk, to the right and left pulmonary veins, to the left atrium which then goes through my bicuspid valve, then into my left ventricle, and then through the semi -lunar valves that lead to my aorta, and all around again.
