The book entitled "Blood Pressure Physiology" will aim to give an overview of the basic hemodynamic concepts of circulation that are connected to blood pressure, as well as to discuss the most relevant mechanisms of normal blood pressure regulation. The normal, physiological regulation of blood pressure is crucial for the normal functioning of the whole organism. In the case of dysregulation, consequences can include serious disorders and health implications, especially if the dysfunction lasts during a prolonged time period. On the other hand, various other disorders can affect blood pressure, and blood pressure is one of the vital signs that healthcare professionals use in evaluating a patient's health. It is, therefore, crucial to view the physiology of blood pressure in the context of the existence of hypertension and other disorders, especially since the prevalence of hypertension is relatively high. This book will discuss relevant scientific knowledge about blood pressure physiology and also intends to introduce the reader to cutting-edge research with an accentuation on the mechanisms at the functional/physiological and molecular/cellular levels.
