1000ESSAY:
Trace a drop of blood through both the systemic and the pulmonary systems. You need to include the major vessels (aorta, vena cava, pulmonary vein, pulmonary artery, coronary sinus) as well as all parts of the heart (ventricles, atria, the four valves). To receive maximum credit, you need to include at least 5 major vessels and what part of the body they supply blood to (that were discussed in class)
