Please the events of the cardiac cycle in order. = #1 Blood continuously flows into both atria. Two thirds of the atrial blood flows passively into the ventricles. The right and left AV valves are closed and the aortic and pulmonary semilunar valves are opened. The pressure of incoming blood opens the right and left AV valves. = The atria contract to pump the remaining blood into the ventricles. = #5 The atria relax, and the ventricles begin to contract. = #8 The ventricles relax, and the semilunar valves are closed. = Ventricular contraction pumps blood into the arteries.

Trace the journey of a drop of blood starting from the right atrium, continuing to the right thumb, and returning to the right atrium. This would include a trip through the heart. Be sure to identify both the arterial and venous vessels as well as all of the relevant structures within the heart. Considering the online nature of this exam, drawings are not required. Simply type in the order of structures with a dash (-) between structures.
