Identifying the Evolutionary Building Blocks of the Cardiac Conduction System
The endothermic state of mammals and birds requires high heart rates to accommodate the high rates of oxygen consumption. These high heart rates are driven by very similar conduction systems consisting of an atrioventricular node that slows the electrical impulse and a His-Purkinje system that efficiently activates the ventricular chambers. While ectothermic vertebrates have similar contraction...

In this chapter, we introduce a highly expressive, self-contained reflective meta-model of object-process methodology (OPM). OPM enables universal system modeling based on the notions of processes that transform objects. Extending the object-oriented approach, which views processes as residents of objects, OPM provides for the existence of stand-alone processes that can represent transformation...
