What is heart action potential?
heart action potential is an event in the exciting tissue of the heart system, which in turn causes muscle contraction necessary for blood distribution. Action potentials are complex processes, but like most things, it can be simplified to make understanding easier. Simply put, the heart action potential is an electrical event caused by a nerve or environmental stimulus responsible for regular contraction or beating of the heart.
Not every cell in the body is capable of action potential. Medical experts call cells in which this electrical event can occur exciting cells and describe their ability to change the states. Electric event is a change in charge of which actually occurs through a physical mechanism. There are gatelike structures that open near and allow certain charged particles in and out of the cell. This particle exchange actually changes the cartridge gradient cells in relation to its external environment and when this gradient reaches a certain threshold,There is action potential.
It is inappropriate to imagine heart action potential as the only event. In fact, there are many action potentials that contribute to the physiological effect whose frequency affects this action itself. The heart action potential is unique from those that occur in other parts of the body due to its self -regulation mechanism. Most action potentials require an external stimulus from the body or environment, while the heart relies on a node system that regularly triggers action potentials. These nodes associated with the nervous system allow the heart regulation as needed.
If one practices, one may need more blood distribution to meet oxygen requirements for physical activity. One way to achieve this is to increase the heart rate of contraction. The nervous system deals with this immediate need and takes steps, causing regulatory nodes of the heart for ÚCertainly create cardiac action potentials. This increase in frequency transmission in the heart chambers, causing more contractions per minute, which increases blood flow to the level necessary to meet physiological requirements.
The human heart is an amazing feature of the body without which life could not exist. The heart relies on heart action potential for its regulation. This is the way the heart can respond to the need for changes, allowing it to keep up with the constantly changing body.
