Can someone explain hemodynamics of cardiac output to me?

thx

Hemodynamics is an important part of cardiovascular physiology dealing with the forces the pump (the heart) has to develop to circulate blood through the cardiovascular system. Adequate blood circulation (blood flow) is a necessary condition for adequate supply of oxygen to all tissues, which, in return, is synonymous with cardiovascular health, survival of surgical patients, longevity and quality of life. To an outside observer (a physician or a nurse) these hemodynamic forces demonstrate themselves as blood pressure and blood flow paired values at different nodes of the cardiovascular system. We will concentrate on systemic hemodynamics - the blood pressure and blood flow at the output of the left heart. The interest in systemic hemodynamics is obvious: A significant majority of all cardiovascular diseases and disorders is related to systemic hemodynamic dysfunction. Hypertension and congestive heart failure are two best known systemic hemodynamic disorders.
