Cardiac physiology: introduction

Each of the body's cells depends on a large number of substances, among which we can find, gases, ions and nutrients, so they also depend on chemical messengers, substances that protect them, and even that the substances that are produced due to Its metabolism is effectively removed, this is achieved thanks to the fact that blood flows continuously and allows the exchange of substances with the interstitial medium and this with the intracellular medium, this complex mechanism is achieved because the heart is capable of generating a difference in pressures between the venous and arterial sides, in the process they take part from the different types of cardiac muscles, the valves of the heart, the smooth muscle of arteries and veins, the endothelium and even the same demand of the cells of the body, in addition to various mechanisms that can include the kidney, the nervous system and others, join us in this series of videos and enjoy the analysis of various canisms that allow us to understand cardiac physiology.
