The heart - the part of your body you surely cannot manage without!
From the immemorial times individuals had a pretty good idea that human heart is such an important source of life, no man or woman could do without it. From those times the heart is a symbol of something entirely important and necessary for the very survival of any personality. That is exactly why our communication is full of word-combinations mentioning the heart.
Persons used to guess that the strength of any man is in the heart. Some tribes were sure human soul is located in the heart, others we sure every thought, either light or cruel, is born in the heart, that is why they believed that a bad personality has a black heart beating in the chest!
“You are my heart” - so we say about the most important person in our life. The man able of fascinating everybody gets the name of “the heart of the company”. When something disappointing happens to our nearest and dearest we always convince them not “to take it all to heart”. A savagedreadful and careless individual is called “heartless”. And if someone really enjoys meals we refer him or her to “hearty eaters”. No doubt you can continue this list with your own examples demonstrating how important is the heart for human beings!
Now armed with every piece of knowledge modern science provides us with we do understand that the heart is nothing but an organ, but it keeps counting throbs in elation when we are happy and continues crying when we have bad periods of our lives. God only knows, maybe that is the reason why dangerous failures in the work of human hearts are responsible for 25% of the total deaths all over the world! Let us find out general tips about the heart to decipher the first symptoms of any heart disorder and to be able to keep your personal biological engine healthy!
The heart just as hearts of all animals, is a hollow muscular organ of the body’s circulatory system. It keeps pumping blood throughout the veins. Its persistent rhythmic contractions pump as much as 5-6 liters of blood every minute, about 360 liters of blood every hour and 8 000 - 10 000 liters of blood daily! Normal contraction rate of any healthy adult personality is about 60-80 a minute, i.e. about 4 500 contractions an hour or 100 000 - 108 000 daily! Sounds shocking, doesn’t it! Docs ofter refer heart diseases to cardiac affairs. The point is term cardiac comes from the Greek “kardia” meaning “related to the heart”. Our hearts are very complicated. Normal work of the heart and different heart disease called cardiopathies are carefully studied by cardiology.
Human heart is divided into four chambers. The two upper chambers are called the left and right atria, while the two lower chambers are called the right and left ventricles. Sometimes physicians speak about the right heart (right atrium and right ventricle together) and the left heart (the left atrium and left ventricle together).
In the majority of cases the heart is as large as a fist, it occupies the major part of the chest, it is slightly shifted to the left and it weighs as much as 250 and 350 grams.
We have already mentioned it above that, the basic function of the heart is pumping blood, but this job is a very difficult affair! The heart always sends our blood in one direction. It goes from the atria to the ventricles and moves on through arteries. Powerful triscupid, mitral, aortic and pulmonary valves in the heart keep the blood from getting backwards. It is extremely important because the heart at the same time sends de-oxygenated blood towards the lungs and oxygenated blood to every system and organ of our body!
The right heart is responsible for collecting de-oxygenated blood in its atrium and pushing it through the ventricle straight into the lungs, where carbon dioxide is dropped off (when we breathe out) and oxygen picked up (when we inhale). This happens with the help of erythrocytes taking part in the process of diffusion.
The left heart is responsible for collecting oxygenated blood from the lungs in its atrium and pushing it through the ventricle and via the aorta out to the body. As you can see, a much greater force is needed to send the blood through the large systemic circulation. That is the reason why the muscle wall surrounding the left ventricle is considerable thicker than that of the right ventricle pumping the blood straight into the lungs.
The main part of people carelessly think their personal biological engine will always serve them and they never do a thing to support it. As some cardiologists say, you have a healthy heart if it never reminds you of the fact it is there, in your chest and keeps working 24/7. It is a pity, persons start thinking about the heart only when it fails them for the first time when it is to late to prevent a disaster.
Do you know what activities, ways of life and behavior damage your unique biological ticker? First of all, stressful jobs and family scandals make your heart beat at a crazy speed. Lack of sleep and relaxation, a stream of evil emotions and the feeling of helplessness make the situation worse. Poor ecology, insufficient recreations give some strain to your heart, too. Junk and fast food, irregular meals and wrong diets do not provide your heart with elements necessary for its flawless functioning. Lack of physical exercise make your heart muscles weaker, as a result your ticker is not always able of managing extra strain. Please, remember that that backbreaking physical activity permanently forces your heart to work at the top of its abilities making it wear out.
Any health troubles you ever experienced or have now affect your heart, too. To guarantee your soon recovery your tireless engine doubles and triples its efforts and keeps pumping blood through your vessels when you are running high temperature, when you are intoxicated or when you have to struggle with some infection! Excess weight, high blood pressure, and high cholesterol greatly increase the risk of getting a heart illness, too.
To help your heart be healthy:
- avoid mental stress and strain;
- try to obtain stable position in life;
- think positive, be optimistic, avoid overreacting;
- walk a lot, go in for some sport;
- choose a well-balanced diet;
- control your body weight and blood pressure.
Please, visit your physician at once if:
- you feel your heart working in your chest;
- you are short of breath without considerable physical activity;
- you have trouble breathing (blood may back up into the lungs);
- you have pain in the chest (meaning the heart muscle is not getting enough blood flow);
- your heart feels unusually big;
- your legs and feet swell (blood is backing up from in the lower body);
- you feel weak (the body and brain do not get enough blood to supply them with oxygen);
- your skin and lips turn blue (too little oxygen is in the bloodstream to supply the cells in the body);
- your heart beats irregularly (palpitations).
Those could be the premonitory symptoms of a heart disease!
Heart disease is a umbrella term for a number of troubles with the heart. MDs use the word cardiopathy. Irrestective of the term, any heart problem means that the biological engine does not work as it should.
The short classification of heart disorders counts congenital heart diseases and acquired heart diseases. Congenital heart diseases are the heart disorders a baby is born with. Acquired heart diseases are those troubles that are developed by people in the course of their lives. The majority of heart diseases are acquired ones.
Cardiologists tell there are three common kinds of acquired heart diseases:
1. The problem with the blood vessels carrying blood to the heart muscle - so called Coronary Artery Disease. The blood vessels in question get thinner, some of them can be blocked, that is why blood cannot flow through them at normal speed, as a result the heart muscle cannot work properly, it becomes weak and thin. In the most difficult cases the blood flow stops altogether and the heart muscle dies. Coronary Artery Disease is believed to be hereditary, but it shows itself if a man smokes or drinks too much alcohol, has a history of diabetes, high cholesterol or hypertension.
2. When the heart cannot pump blood at normal levels we speak of Congestive Heart Failure. In some cases the valves of the heart do not let through enough blood because they are too thin. They can let some blood get backwards in the wrong direction, i.e. inside the heart. Forced to do extra work, the heart gets tired or fatigued and its muscle becomes too worn out to cope with any serious strain.
3. The problem with electrical activity in the heart is known as Bad Heart Rhythms. The heart can beat too fast or too slow without any plausible cause. The point is our heart can pump the blood well only if it has normal rhythm. Otherwise this task becomes next to impossible. With the fast rhythm the heart does not have enough time to let the right amount of blood into the chambers, as a result the ticker pumps too little blood with each beat. With the slow rhythm the heart does not make enough contractions to supply the body with the proper quantity of blood. Extremely bad heart rhythms can prevent the heart from pumping any blood at all.
The irony is that your tireless ticker can become the reason of your immediate death! But in fact the things are not as bad as that! Day by day modern pharmacology keeps saving hundreds of lives of men and women having various heart diseases.
