CARDIOVASCULAR PHYSIOLOGY; PART 2 by Professor Fink.wmv

In this Video Lecture, Professor Fink describes the Regulation of arterial Blood Pressure by the Cardiovascular Reflex Center in the Medulla Oblongata. The Baroreceptor Reflex is explained and the 4 major actions identified: [1] change in Heart Rate; [2] change in myocardial contractility; [3] change in venoconstriction; and [4] change in overall degree of arteriolar vasoconstriction. Reference is made to the carotid and aortic baroreceptors, tachycardia, Starling’s Law, Stroke Volume, Cardiac Output, and to Total Peripheral (Vascular) Resistance.

For a more detailed description of how gravity affects your Blood Pressure and how the Baroreceptor Reflex compensates for standing upright, and what Postural (Orthostatic) Hypotension is, watch Professor Finks’ Video Lecture:
