The "nodes" in the heart are the sinoatrial, or SA, node, which is found in the R atrium and is considered the primary pacemaker of the heart. The atrioventricular node, or AV node, is located in the right atrium just above the medial leaflet of the tricuspid valve. It allows for the electrical impulses generated in the atrium to be transmitted to the ventricles and to cause ventricular contraction.

Lymph nodes basically act as filters to clean the extracellular fluid before it reenters circulation, and is part of the immune system where white blood cells mature. There are also nodes like the sinoatrial node (SA) and the atrioventricular (AV) node. They are what act as pacemakers for your heart, driving the periodic electrical impulses that cause a heart beat.
