Step 2: Blood is pumped to the lungs to pick up oxygen. Step 3: Oxygenated blood returns to the left side of the heart. Step 4: Blood is pumped out to the rest of the body to deliver oxygen. Step 5: Deoxygenated blood returns to the right side of the heart to Show more…

Complete each sentence by dragging the labels to the appropriate blanks. Then place each sentence in a logical order beginning with blood entering the right side of the heart. From the right atrium, the wave of depolarization disperses through the myocardium of the atria. The AV node fires, causing the signal to travel into the ventricles as it passes through the AV bundle branches. Depolarization then arrives at the node located in the inferior interatrial septum. Making a U-turn at the apex of the heart, the signals are then carried by the purkinje fibers through the exterior walls of the ventricles. The contraction of the heart begins with autorhythmic depolarization of the pacemaker node located in the superior portion of the posterior atrial wall. The signals then reach the semilunar valves.

Complete each sentence by dragging the labels to the appropriate blanks. Then place each sentence in a logical order beginning with the sinoatrial node. The SA node fires, causing the signal to travel into the atrioventricular node located in the inferior interatrial septum. From the AV node, the signal passes through the bundle of His located in the superior portion of the posterior atrial wall. Depolarization of the bundle of His leads to the activation of the Purkinje fibers. Making a U-turn at the apex of the heart, the signals are then carried by the Purkinje fibers through the exterior walls of the ventricles. The depolarization wave spreads through the ventricles, causing them to contract.
