The heart is the power pump of blood circulation in the human body, it is uninterrupted to beat, maintain the normal operation of blood circulation, ensure the blood oxygen supply of tissue cells, and life activities can be carried out normally. Once the beating of the heart stops, life activity will also stop. Especially when people reach middle age, they should pay more attention to nourishing their hearts. Teach you a few tips today, collect it and have nothing to look at.
Have a bad heart and eat less of these foods
1. Pickled and smoked egg yolk foods
Salted duck eggs
The cholesterol content in egg yolks such as salted duck eggs and tea eggs is much higher than that of ordinary egg yolks, especially those with hyperlipidemia and heart disease, and the intake of such foods must be strictly controlled in the diet. In addition, everyone knows that the salt content in salted duck eggs is also very high, and the blood pressure is easy to rise when eating too much, which will greatly increase the incidence of myocardial infarction.
2. Fried foods
Studies have shown that people who regularly consume fried foods are more likely to have heart disease, which is mostly coronary heart disease caused by coronary atherosclerosis. In addition, frequent intake of fried food will lead to the deposition of cholesterol in the human blood in the coronary artery blood vessel wall, resulting in stiffness of the tube wall, decreased elasticity, plaque formation, and lumen narrowing, which is an important cause of hyperlipidemia.
Extended reading: Why does the heart keep beating?
We may all know that the various movements of our hands, feet, and limbs are consciously carried out under the control of the brain of the supreme command of the human body, and he is intermittent, only when our brain sends out a command signal, this command signal is transmitted to the corresponding skeletal muscle through nerve fibers, causing the contraction of skeletal muscle, and then causing the corresponding movement of the limb. If the brain doesn't send out command signals, the skeletal muscles don't contract and the limbs don't move. If the brain loses brain function due to trauma, bleeding, infarction, can not send command signals or conduct fiber destruction, can not transmit the brain's command signals to the skeletal muscles, skeletal muscles will not contract, limbs will be paralyzed.
The heart is the power pump of blood circulation in the human body, it is uninterrupted to beat, maintain the normal operation of blood circulation, ensure the blood oxygen supply of tissue cells, and life activities can be carried out normally. Once the beating of the heart stops, life activity will also stop. The beating of the heart is uninterrupted and is not controlled by the consciousness of the brain. So why does the heart keep beating? This is because there is a command system inside the heart itself, which can automatically and continuously issue command signals to control the contraction of the atrium and ventricles. Medically, this command system is called a special pacing conduction system or a conduction system.
The conduction system includes the sinus node, the internodular bundle, the atrioventricular node, the atrioventricular bundle, the left and right bundle branches and their branches, and the Buconye's fiber. The sinoatrial node is the supreme command of this chain of command, and he has the highest self-discipline and the fastest frequency of agitation, that is, the ability to produce command signals is the strongest. The atrioventricular node has lower self-discipline and a slower frequency of agitation, equivalent to a secondary command; other parts of the conduction system are less autonomous and produce a slower frequency of agitation, equivalent to a lower command. Normally, the heart's command signals come from the sinoatrial nodes. The sinoatrial node can automatically and uninterruptedly issue command signals, and sequentially convey them to the atrium and ventricles through other parts of the conduction system, which in turn causes the coordinated contraction of the atrium and ventricles, which ensures the continuous and uninterrupted beating of the heart and maintains the normal progress of life activities.
