The heart is one of the important organs in the human body. It also has all living organisms that have a developed circulatory system. Various venous trunks adjoin the heart, which pump blood into the arteries. The entire cavity is divided into 2 atria and 2 ventricles. The left side forms the "arterial heart", and the right - the venous.
It is worth noting that the shape of the heart is different for everyone. This is influenced by such factors: physique, age, state of health. The mass of the organ in men and women has a different weight. In the male, the mass reaches about 332 grams, and the female - about 253 g.
In this article, we will cover 10 interesting facts about the heart.
10. The condition of the oral cavity affects heart health
Not many people know that having healthy teeth is very important. They have a huge impact on the whole body. Very often, if a person has problems with his teeth, then this can lead to serious diseases.
These include heart disease. Constant tooth pain raises blood pressure. And this, in turn, can affect the heart. Taking painkillers can cause even more harm to your health.
If you do not treat your teeth systematically, then there is a risk of complications. Do not be afraid of dentists, now we use the highest quality materials and equipment. The treatment is completely painless for a person.
Many heart diseases are completely asymptomatic. Various infections that are in the cavity of diseased teeth can carry serious diseases into the blood. Rheumatism, endocarditis, cardiomyopathy and much more.
9. A female heart beats more often than a male
Scientists have long proved the fact that a female heart beats much more often than a male. Under normal circumstances, a woman's heart can beat more often by eight to ten contractions. That is why the pulse is 80-90 beats per minute. But in the male population, the heartbeat is about 65-75 beats.
This is explained by the fact that the female heart is much smaller and has a slightly different shape. It is in the form of an oval, and in men it looks like a cone.
It is worth noting that women carry loads much easier. Also, many stresses do not affect their body so much. The heart is also arranged so that it has some protection against heart attacks and strokes. But men are more prone to such diseases.
8. Obesity Affects Heart Function
Recently, doctors are increasingly faced with heart disease due to overweight people. Extra pounds are deposited not only on the abdomen, hips, but internal organs also suffer greatly from this.
As a result of this, a double load goes on the heart. Shortness of breath begins, chest pain, arrhythmia, tachycardia and much more. Blood circulates harder, stagnation appears in the circles of blood circulation.
It is worth noting that if a person suffers from a more complex form of obesity (3-4 degree), then the heart changes its structure greatly. In some cases, you can even notice the appearance of adipose tissue on the organ.
You can get rid of this in only one way, urgently losing weight. Adipose tissue will begin to go away not only externally, but also internally. The condition of a person will begin to change for the better.
7. Diastole - a pause of 0.4 seconds, so that the body relaxes
Each person’s heart cycle consists of a pause called a “diastole”. This is a kind of relaxation of all parts of the myocardium, as well as some valves.
The average purity of contractions in humans is from 60 to 80 strokes. Diastole only takes 0.4 seconds. There is also systole, which is given 0.1 s.
During diastole, all leaf valves are open. Venous blood enters the atrium, and then partially passes into the ventricles.
6. The human heart is as close as possible to the heart of a pig
It has long been known that a pig has a structure quite similar in human anatomy and physiology. The heart and blood vessels of the animal are similar to human. It is worth noting that even hemoglobin and protein levels in the blood coincide.
Coincidences are found among teeth, eyes, and also the liver, kidneys, and even the heart. The mass of this organ is 320 grams, and a person has 300 grams. Many diseases are similar to human ones. For example, newborn piglets may have the same diseases as young babies.
5. Oily fish, nuts, tomatoes and garlic are good for the heart.
Not many people know that there are products that are very useful for our heart and its work. These include, for example, whole grains - rice, oats, barley, buckwheat. They help lower cholesterol.
Among the berries will be useful - strawberries, raspberries, blackberries. Cell functions, blood coagulation improve. It also helps to regulate the pressure.
Fatty fish - salmon, mackerel, tuna, contain a large amount of omega acids, which positively affect heart health. It should be consumed only 2-3 times a week.
Nuts such as almonds, walnuts, hazelnuts will also help lower blood cholesterol and lower blood pressure.
4. The organ can function outside the body
Once, one of the most significant discoveries was made. A person’s heart can “work” normally outside the body for about 8 hours.
The heart was placed in a special container where a low temperature was observed. Scientists installed tubes on the organ through which blood flowed to it. Thus, it continued to work for eight hours.
Scientists note that this is very important, as there are many patients who very urgently need to transplant a donor organ. Heart sampling is possible only for a very small amount of time after the death of a person.
It is worth noting that this is how many lives were saved. In the US, this technology is still completely new. They have not used it yet. But in the UK and Australia, this has long been practiced.
3. The blue whale has the largest heart on the planet.
The blue whale is the largest mammal that lives in the seas and oceans. Scientists have long tried to study the structure of his body and organs.
Lungs have a truly amazing property. A whale can hold its breath for an hour. For it to recover, he just needs to come out. The lung volume is about three thousand liters.
But the circulatory system of this creature is even more unusual. The vessels of the heart are very large, the diameter of one aorta can be up to 40 centimeters. But the organ itself is considered the largest in the whole world. It weighs about a ton.
2. In 1967, an organ transplant was successfully performed for the first time.
The first heart transplant operation was performed on December 3, 1967. It was produced by a surgeon named Christian Barnard.
The patient needed a heart transplant, as his heart muscle was severely affected by the disease. During a car accident, one of the passengers died, it was his donor organ that was transplanted to the person.
The work was very difficult. But surprisingly, the heart began to beat. The next day, Christian became known throughout the world.
1. Laughter has a positive effect on the work of the heart
No wonder they say that laughter prolongs life. It makes a person feel completely different. Under its action, the hormone of stress and tension decreases, and the immune system is also strengthened.
Scientists have long proven that laughter has a positive effect on heart function, the nervous system, and indeed the whole organism.
