(*Do this as a numbered LIST, not an essay, starting with 1. Superior and Inferior vena cava and coronary sinus 2. ____________ 3. ____________ 4. ____________ until you reach where the drop of blood leaves the heart and is on its way to the body tissues of the systemic circuit. Remember to: LIST ALL of the specific named blood vessels and the names of any types of blood vessels in the correct order that the drop of blood would flow through them.
