The book Selected Topics in Blood Pressure Physiology aims to provide up-to-date insights into the regulation of arterial blood pressure and insights into regulatory dysfunction connected to hypertension. It includes discussions on various topics such as hemodynamics and the fundamental mechanisms of blood pressure regulation, such as the baroreceptor reflex, as well as mechanisms connected to pressure natriuresis, but also delves into discussions about hypertension and its consequences into the causes and pathophysiology of secondary hypertension, as well as into potential effects of lifestyle changes on blood pressure regulation. The book intends to be one of many "stepping stones" on the long way to a better understanding of blood pressure regulation and dysfunction, which is a prerequisite to achieving better clinical results, including reducing cardiovascular morbidity and mortality. The book aims to inspire readers to further their thinking and research in this area.
