Cardiovascular disease is a major cause of death in the world. Understanding the basic flow of blood through the cardiovascular system and learning about the electrical conduction system is vital to understanding future pathology. Cardiovascular function is often described through the variables that alter vasodynamics. Students can expect to identify these variables and explain the factors that influence them in order to examine the physiology of the cardiovascular system.
