2. Trace the path of a drop of blood, starting at the right atrium and returning to the right atrium, through the pulmonary and
systemic circuits of the cardiovascular system. Identify the chambers, valves, and vessels (except specific systemic blood vessels that are not directly associated with the heart)
right atrium - tricuspid value - right ventricle - pulmonic value - pulmonary artery - lungs - pulmonary vein - left atrium - mitral valve - left ventricle - aortic value - aorta - all systems- right atrium.
