10 interesting facts about the heart – one of the most important human organs

The heart is one of the important organs in the human body. All living organisms that have a developed circulatory system also have it. 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 side forms 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 sex, the mass reaches about 332 grams, and in the female – about 253 g.

In this article, we will look at 10 interesting facts about the heart.

10 Oral Health Affects Heart Health

Not many people know that having healthy teeth is very important. They have a huge impact on the entire body. Very often, if a person has problems with his teeth, this can lead to serious diseases.

These include heart disease. Constant pain in the teeth increases 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 the highest quality materials and equipment are used. 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 more.

9. A woman’s heart beats faster than a man’s

Scientists have long proven the fact that a woman’s heart beats much faster than a man’s.. Under normal conditions, a woman’s heart can beat eight to ten times faster. 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 in size 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 endure stress much easier. Also, many stresses do not affect their body so much. The heart is also arranged in such a way that it has some protection against heart attacks and strokes. But men are more susceptible 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 stomach, hips, but internal organs also suffer greatly from this.

As a result, there is a double burden on the heart. Shortness of breath, chest pain, arrhythmia, tachycardia and much more begin. The 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 (grade 3-4), then the heart greatly changes its structure. In some cases, you can even notice the appearance of adipose tissue on the organ.

There is only one way to get rid of this, urgently losing weight. Adipose tissue will begin to go off not only externally, but also internally. The human condition will begin to change for the better.

7. Diastole – a pause of 0,4 seconds for the organ to relax

Each person’s cardiac cycle consists of a certain pause, which is called “diastole”. This is a kind of relaxation of all parts of the myocardium, as well as some valves.

The average purity of contractions in a person is from 60 to 80 beats. Diastole takes only 0,4 seconds. There is also a systole, which is given 0,1 s.

During diastole, all cuspid valves are open. Venous blood enters the atrium, and then partially passes into the ventricles.

6. The human heart is as similar as the heart of a pig

It has long been known that a pig has a structure that is quite close in anatomy and physiology to a person. The heart and vessels of the animal are similar to human. It is worth noting that even the levels of hemoglobin and protein in the blood coincide.

There are coincidences among the teeth, eyes, as well as the liver, kidneys and even the heart. The mass of this organ is 320 grams in them, and in humans 300. Many diseases are similar to human ones. For example, piglets that have just been born may have the same diseases as small infants.

5. Fatty 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 levels.

Among the berries will be useful – strawberries, raspberries, blackberries. Improved cell function, blood clotting. It also helps to regulate pressure.

Fatty fish – salmon, mackerel, tuna, contain a large amount of omega acids, which have a positive effect on heart health. You need to use only 2-3 times a week.

Nuts such as almonds, walnuts, and hazelnuts will also help lower blood cholesterol and lower blood pressure.

4. The organ can function outside the body

One day, one of the most significant discoveries was made. The human 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 to 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 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 quite new. It is not being used yet. But in the UK and Australia, this has long been practiced.

3. The blue whale has the biggest 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.

The lungs have a truly amazing property. A whale can hold its breath for an hour. In order for it to recover, it just needs to come out. The volume of the lungs 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 body itself is considered the largest in the world. Weighs about a ton.

2. In 1967, the first successful organ transplant was performed.

The first heart transplant was performed on December 3, 1967.. It was made 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 a person.

The work was very difficult. But surprisingly, the heart began to beat. The next day, Christian became known to the whole world.

1. Laughter is good for 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 strengthened.

Scientists have long proven that laughter has a positive effect on the work of the heart, the nervous system, and in general, the whole organism.
