Where does the heart s power come from? What is the source of cardiomyocyte power

Hello dear and happy to answer for you. You can also find out that the source of power of cardiomyocytes is: the source of power of cardiac lead wax", which can not only help cardiomyocytes obtain sufficient oxygen, assist in preventing or alleviating some sudden heart diseases, but also prevent the peroxidation of lipid and protein, remove free radicals, and protect the cardiovascular system.

The above is all my reply, I hope it can help you, I wish you a happy life

What kind of friendship is the heart to tell the number of dirty heads?

The heart beats because the sinus node has autonomic cells, and it will spontaneously emit nerve impulses, which are transmitted to the atrial and ventricular cells through special conduction pathways, causing them to contract and relax, and induce blood. He is not controlled by subjective consciousness. In addition to the sinus node, there are also some cells that are automatic, but not as strong as it, so the heartbeat is generally determined by the rhythm of the sinus node and is affected by other factors.

The result is 75 points for ordinary people.

Breathing has two parts: inhalation and exhalation, the specific mechanism, medically also has a fully recognized statement, but through experiments, it has been confirmed that breathing is mainly controlled by the pons segments, and the vagus nerve is also involved, natural breathing is controlled by autonomic nerves, by the mechanism of self-discipline, and there is also a mechanism of human feedback, for example: usually we do not realize that we are breathing that is the embodiment of self-discipline, when strenuous activity, the breathing deepens and accelerates, that is the feedback mechanism at work, on the pons There is also a more advanced control system, the human cerebral cortex can also control breathing, such as forced breath-holding, but it is not commonly used, this is only used by people in special circumstances so breathing will also be subjectively controlled, and vegetative people can also rely on their autonomic breathing.

When self-discipline is disrupted, the person must control his breathing, and when he falls asleep, if he does not have a ventilator, he will suffocate to death.

self-sufficient". Because in each cardiomyocyte, there is a structural component called mitochondria, which are numerous, and these mitochondria produce energy and transmit it to cardiomyocytes for use. People get nutrients from the diet every day, and the glucose and fatty acids that are digested and absorbed into the blood circulation are of course also brought to the heart muscle cells, and at the same time bring fresh oxygen, at this time, the mitochondria are active, just like a skilled technician operating a precision instrument, oxidizing and decomposing the glucose and fatty acids that come to them, turning them into water and carbon dioxide, and in this process, the energy substance - adenosine triphosphate (ATP) is produced, and is transmitted to the myocardial fibers as the energy power of contractile activity. This process is continuous.

In this way, mitochondria have really become the "power processing plant" of cardiomyocytes.

Because cardiac activity requires sufficient energy supply to ensure that cardiac activity is ensured, myocardial cells also contain the most abundant mitochondria, which can account for more than half of the total volume of myocardial cells. With sufficient energy as a guarantee, the heart muscle can move regularly day and night.

However, when the blood vessels are atherosclerosis and there is a blockage in the blood vessels, the blood supply is insufficient, the energy is insufficient, and the mitochondria are difficult to cook without rice, resulting in insufficient energy, weakened heart activity, and weak contraction.

Experimental studies have found that the symptoms of palpitation, shortness of breath and angina pectoris are caused by coronary heart disease, and an important change in heart damage is the decrease in the number of mitochondria in cardiomyocytes, the insufficient operation of power processing plants, and the shortage of energy for heart activity. The more severe the mitochondrial damage, the more severe the symptoms of coronary heart disease. At this time, only by promoting the recovery of mitochondria, increasing the number of mitochondria, and having sufficient energy, can coronary heart disease be fundamentally prevented.
