Why Does the Heart Continue to Beat Out of the Body
Why does my heart beat all day long without getting tired?? The heart is a very important part of the human body. It works continuously to transport blood to all parts of the body. Without the heart, the body would not be able to function. Therefore, the role of this department is further emphasized. Surely many people will wonder: why does the heart work for life without getting tired? The information below will certainly be useful to you.
Know the heart part of the body
First, we need to learn about heart disease first so that we can draw the most accurate conclusions.
1. Structure and function of the heart
Why does my heart beat all day without feeling tired?
The heart is a very important part of the circulatory system. The heart is made of a very special type of muscle called cardiomyocytes. The heart is a hollow muscle and its structure is divided into 4 chambers: two atria and two ventricles. The right atrium and the left atrium have thin walls that receive blood from the veins into the ventricles. Next, the right and left ventricle begin to pump blood into the arteries at a very high pressure. The atria are separated by the interventricular septum, and the ventricles are separated by the interventricular septum.
The thickness of the walls of the heart in each chamber varies according to its function. For the heart muscle in the left ventricle, it will be 2 to 4 times thicker than the wall of the right ventricle, because when pumping blood at a higher pressure to be able to overcome the resistance of the circulation.
2. Heart valve system
Heart valves are very thin, flexible connective tissue enclosed in the membrane of the heart.
Atrioventricular valve: Between the atria and the ventricles, the left is the mitral valve and the right is the tricuspid valve, which helps blood flow in one direction from the atria to the ventricles. The muscular columns are connected to the atrioventricular valve by ligaments. The shaft of the muscle will contract when the ventricle contracts and will not help the valve close, and will help pull the valve stem toward the ventricle. This will prevent the leaflets from protruding into the atria during ventricular contraction. If the ligaments are torn, then when the ventricles contract, blood can flow back into the atria, causing the heart to weaken.
The semilunar valve: between the left ventricle and the aorta is the aortic valve, and between the right ventricle and the pulmonary artery is the pulmonary valve. It helps blood flow in one direction from the ventricles to the arteries.
Heart valves operate with a passive opening and closing mechanism, depending on the pressure difference between the valves.
3. Myocardial fibers
The heart is made up of three types of cardiac muscle: atrial and ventricular muscle, along with very specific excitatory and conductive muscle fibers.
Cardiomyocytes are intermediate in their characteristics from striated and smooth muscle cells, which are very small, striated and also branched and have only one nucleus. Unlike striated muscle, cardiomyocytes have bridges attached to each other in a very solid mass, with some parts of the cell membrane fused together. Myocardial fibers, which are myocardial in nature, are activated in response to stimulation or to rapidly transmit electrical potentials between myocardial fibers through junctions. The conduction of electrical potential from the atria to the ventricles is called the atrioventricular conduction, and it is conducted through a very specific conduction pathway.
The heart will take on a very important job, i.e. the heart pumps blood along the arteries to transport oxygen and nutrients throughout the body. It also sucks blood from the veins to the heart, then proceeds to push the blood into the lungs to exchange carbon dioxide and get O2.
Why does the heart work for life without getting tired?
Heart – The heart muscle is very strong, flexible and durable.
The heart muscle operates under the control of the autonomic nervous system.
The heart contracts and expands in cycles
The systole time of the heart is about 0.8 seconds.
+ Atrial systolic phase: 0.1 sec (rest time 0.7 sec)
+ Ventricular contraction: 0.3 seconds (rest time 0.5 seconds)
+ General extension period: 0.4 seconds (0.4 seconds interval)
Normal heart rate is 75 revolutions per minute.
The heart will work in cycles, and each cycle is divided into phases. At the same time, there is also a certain rest period between these cardiovascular stages. Rest time and heart time are roughly the same. That is why we can confirm this: the heart works for life without getting tired because the heart has a very reasonable time to work and rest.
Above is the information to be able to answer the question: why does the heart work for life without getting tired? We hope the basic information we share here will be useful to you. Always stick to the right diet, and get enough rest to keep your heart performing at its best!
Although the heart is a machine that works tirelessly day and night, as man ages, the machine also gradually reaches its limits. That's why most old age diseases die from heart disease, for a healthier life you can benefit from it. Full body massage chair For the prevention of cardiovascular disease or if you already have it, they can be used in combination with therapeutic drugs to improve the healing effect.
Why does my heart beat all day without feeling tired? The heart is a very important part of the human body. It works continuously to transport blood to all parts of the body. Without the heart, the body would not be able to function. Therefore, the role of this department is further emphasized.
The heart beats tirelessly all day long due to time shrinkage, a job low degree heart and regular rest periods. Moreover, the structure heart Very special and durable for the body heart This is how it nourishes the blood heart always abundant. Rest periods can be seen and a job low degree heart almost equal.
With the best solutions to know the structure and function of the heart, and how to help the heart beat throughout the day without getting tired.

B. Explain why the heart works for life without getting tired?
The cardiac cycle is the activity of the human heart from the beginning of one heartbeat to the beginning of the next. The three-phase active cardiac cycle is 0.8 seconds
Heart – The heart muscle is very strong, flexible and durable.
The heart muscle operates under the control of the autonomic nervous system.
The heart contracts and expands in cycles
The systole time of the heart is about 0.8 seconds.
+ Atrial systolic phase: 0.1 sec (rest time 0.7 sec)
+ Ventricular contraction: 0.3 seconds (rest time 0.5 seconds)
+ General extension period: 0.4 seconds (0.4 seconds interval)
Normal heart rate is 75 revolutions per minute.
The heart will work in cycles, and each cycle is divided into phases. At the same time, There is a certain rest period between these cardiac stages. Rest time and cardiac activity time are approximately equal. That is why we can confirm this: the heart works for life without getting tired because the heart has a very reasonable time to work and rest.
Because the rest time for each chamber of the heart is longer than the working time. As a result, the heart works throughout life without fatigue. Thus, if we used to get enough sleep, the heart will work well and stay healthy. All parts are the same, if you work day and night carefully you will not feel tired, but if you are not well taken care of, your stamina will weaken, and as you get older. slow down too. Therefore, due to the high workload of young people, irregular eating and sleeping habits are the cause of many elderly people with cardiovascular disease.
c. How do you keep your heart healthy?
- Exercise: Exercising regularly for 30 minutes a day, 5 times a week will help keep your heart healthy and help you lose weight quickly. Say No To Tobacco, Pipe Tobacco: Smoking tobacco, pipe tobacco can increase the risk of coronary heart disease. Therefore, it is recommended to quit smoking as soon as possible to avoid harmful substances entering the body and harming the heart Build a healthy diet: Add foods that are good for the body such as fish, vegetables, fruits … to reduce fat, salt and calories. Choose lean meats and low-fat dairy products and avoid junk foods as they are high in salt and fat. Reducing stress and pressure: Stress affects the cardiovascular system. When stress activates the sympathetic nervous system, it increases the activity of the heart and blood vessels, increases blood pressure, and increases the amount of blood that is pumped to the organs of the body. Limit alcoholic beverages: Not only does it cause alcohol dependence, beer also contains many calories, which can easily lead to weight gain, affecting the heart. Sleep on time: Eating and sleeping on time will help, and not sleeping late will help the body to be healthier. Regular medical exams: Regular medical exams will help you monitor health conditions such as blood pressure and blood cholesterol and prevent and treat cardiovascular disease.
