生理学复习笔记03血液循环（Physiology review notes 03 blood circulation） Syllabus requirements 1., the pump function of the heart: cardiac cycle, the process and principle of cardiac pump blood, evaluation and regulation of cardiac pumping function, heart sound. 2. the bioelectric and physiological characteristics of the myocardium: the bioelectric phenomenon of the myocardium and its brief principle, the electrophysiological characteristics of the myocardium, and the effects of the autonomic nerve on the bioelectric activity and contractile function of the myocardium. 3. vascular physiology: the relative stability of arterial blood pressure and its physiological significance, the formation and influencing factors of arterial blood pressure. Venous pressure, central venous pressure, and factors affecting venous return. Microcirculation. Formation and reflux of tissue fluid and lymph. 4. regulation of cardiovascular activity: the innervation and function of the heart and blood vessels, the cardiovascular center, carotid sinus and aortic arch, baroreceptor reflex, chemosensory reflex, and other reflexes. Humoral and autoregulation of the heart and blood vessels. Regulation of cardiovascular activity during muscle movement. Long term regulation of arterial blood pressure. 5. blood volume and its regulation: volume of nerve and body fluid regulation, physiological response to acute blood loss. Essentials of syllabus I. cardiac cycle and heart rate 1. concept: a contraction and relaxation of the heart constitute a mechanical cycle called the cardiac cycle. Since the ventricles play a major role in cardiac pumping, the cardiac cycle usually refers to the ventricular cycle. 2. heart rate and cardiac cycle: Cardiac cycle length and heart rate range, increased heart rate, cardiac cycle shortened, systolic and diastolic are shortened, but the diastolic shortened the proportion of larger, relative prolongation of working time, the heart rate will affect the pump function of the heart. 3. h
