How Much Does A Human Heart Weight?
In this article, We talk about How Much Does A Human Heart Weight? We share with you some informative tips about the human heart Weight .
Exciting Facts About The Heart
- A healthy adult’s heart weighs around 300-350 grams. A blue whale’s heart weighs around 600 kg to a ton.
- In the case of a situs inversus, the heart is inverted on the right side. This anatomical peculiarity is found only very rarely in one in Eight thousand-twenty five thousand people
- When resting, the healthy heart beats between 50 and 80 times a minute. This frequency can increase up to 220 beats per minute under exertion. During the night, the heart rate drops to 45 to 55 beats per minute. In the course of an average human life, around 3 billion heartbeats come together.
- A shrew’s heart beats between 500-1200 times per minute.
- Women’s hearts beat faster than men’s hearts
- The heart pumps approx. 6 to 8 liters of blood through the blood vessels every minute.
- The human heart creates enough pressure to squirt blood up to 10 meters high directly from the body.
- In the course of life, around 250 million liters of blood are pumped through the body. Enough to fill approx. 3 supertankers with it.
Location and functioning of the heart
The human heart is about the size of a fist and sits almost in the middle of the chest, roughly between the second and fifth ribs. Since it is slightly sloping, part of it touches the left side of the chest – that’s why many people automatically reach there when their heart is at stake. The heart is enclosed by the pericardium and separated from both lungs by the pleura adjacent to the side.

lies the diaphragm, which is fused with the pericardium. From the front, it is mainly protected by the sternum.
The heart keeps the blood flow and circulation moving. The heart is the engine of life. A pumping station of unmatched endurance and precision. It beats tirelessly – seventy to eighty times in a minute. 100,000 times a day, more than 2.5 billion times in 70 years!
ANATOMY OF THE HEART
Its power and adaptability to the most diverse requirements are incomparable. So far, technology has not produced any machines that could achieve such a performance with a comparable benefit over seventy years.
The heart has a kind of its own “power station” that supplies the electricity for the pumping work for a lifetime. The initial spark for a heartbeat comes from the so-called sinus node, which is, so to speak, the pacemaker for the heart to keep going and pumping blood.
The heart is about the size of a strong fist and weighs about 300 grams and consists of four chambers of the heart. The two large chambers are also called “ventricles”, the two small chambers “atria”. The valve mechanisms of the heart valves ensure that the blood only flows in one direction. The heart muscle itself supplies the coronary arteries with energy.
The heart of an adult is about the size of a loosely clenched man’s fist, in the shape of a truncated cone, and weighs, slightly differently in women and men, between 280 and 320 grams two-thirds on the left, one-third on the right. The apex of the heart points to the bottom left. The lower part of the heart rests on the diaphragm, which separates the chest and abdomen, and it is framed on both sides by lung tissue. The diaphragm’s breathing moves the heart up and down, creating a type of massage that can encourage blood flow to the heart.
Weight Of Heart In Male And Female
Size is the first difference between the heart of a man and a woman. A man’s heart is bigger than a women’s.6 Differences between men’s and women’s hearts mention below.
6 Differences Between Men’s and Women’s Hearts
The physical and hormonal peculiarities mean that, in cardiac matters, there are some differences between the heart of men and that of women that we must take into account when taking care of cardiovascular health. We tell you everything you need to know about the difference between the male and female heart.
1. The size: Men’s heart is bigger than women’s
Size is the first difference between the heart of a man and a woman. Although it does not happen in all cases, in general, the male physical constitution is larger than the female ones, and this characteristic also carries over to the heart and arteries, which are usually smaller in women than in men. Those responsible for this size difference are the sex hormones since male testosterone enlarges the size of the arteries and female estrogens reduce it.
What consequences does the size of the heart have on cardiovascular health in men and women? The smaller size of the arteries puts a woman at greater risk of blood clots or arterial blockages, and it also makes it more difficult for angioplasty or bypass surgery to be performed.
Another cardiovascular consequence of this difference in arterial size is that more migraines and inflammatory diseases occur, pathologies that tend to be more frequent in women.
2. Difference in heart rate in men and women
The heart of the woman pumps about 63 ml. of blood per beat. Since the ideal volume of circulating blood (volume) is approximately 5-6 liters, it takes about 79 beats per minute to reach it. Men, however, typically pump 75 ml. per beat, so they only need 67 beats per minute to reach that ideal volume.
The Heart rate to the number of times the heart beats in 1 minute. The normal value for an adult at rest varies between 60 and 100 beats per minute, depending on sex, age, lifestyle, and the pathologies suffered.
Roughly, up to two years of age, the rate ranges between 120 and 140 bpm. Between the ages of 8 and 17, it goes from 80 to 100 bpm. In the case of adults, between 70 and 80 bpm for sedentary people and between 50 and 60 for those who practice sports or are over 65 years of age.
Heart rate and rhythm in women
If we focus on sex, when the heart rate is excellent, it ranges between 60 and 65 bpm from 18 to above 65 years, with peaks between 18 and 25 and 46 and 55 years.
If it is good, it moves between 65 and 69 bpm; the normal is between 73 and 78 bpm. Above this, it is considered not recommended, and more dangerous as it increases.
Heart rate and rhythm in men
In the case of men, the heart rate is more irregular than for women, with a decrease between the ages of 25 and 35, to later increase, until reaching 65, which decreases again.
It is considered excellent when it is between 56 and 63 bpm; good if it is between 62 and 67 bpm; normal ranges from 70 to 76 bpm. The above is considered harmful.
Why do women have more heartbeats than men?
In general, women have about 10 beats per minute more than men. The reason is that the heart of these has a smaller size. Therefore, the amount of blood that is pumped in each beat is less. To compensate, what it does is beat faster. As a curiosity, when a woman is pregnant, the heart rate increases even more, since the amount of blood that needs to be pumped increases.
3. Arterial problems
In both men and women, heart attacks occur due to arterial problems, although there are differences between the two sexes regarding the type of plaque that forms, the way it accumulates, and the areas where it is usually deposited.
In men, plaque is usually harder and more calcified and tends to accumulate irregularly, so heart attacks usually occur due to the blockage of the arteries due to the lesions that this type of plaque produces in the arterial walls.
In the case of women, the plaque is usually softer and is deposited on the arterial walls in a more homogeneous way, which gradually produces an erosion in these walls that causes a heart attack.
4. Symptoms of heart attack
According to the Spanish Heart Foundation, classic symptoms include oppressive pain in the center of the chest or in the epigastric area (stomach), which can radiate to the left arm, both arms, neck, jaw, and/or back; They can also include sweating, nausea, and shortness of breath.
However, the symptoms in women can be different and more varied, which complicates their diagnosis: unusual fatigue, shortness of breath, cold sweat, or epigastric pain. The days before they can suffer insomnia, anxiety, or weakness.
The passage of time always affects the body, but in the case of women, there is a very clear turning point: the menopausal period. The estrogens that it produces during the fertile stage have a cardioprotective effect, but as we age the production of these hormones is reduced, which leaves the female heart more unprotected and sensitive, and increases the risk of a heart attack.
This circumstance also implies a difference, and that is that women tend to have coronary heart disease approximately ten years later Than men. However, the prognosis of a heart attack is usually worse in women: the percentage of death before reaching the hospital is higher (52% compared to 42% in men) and the prognosis after hospitalization is also worse. On the one hand, because being older than men they tend to have other associated pathologies (kidney disease, osteoarticular disease, anemia …) that complicate the clinical picture.
On the other hand, as the symptoms of a heart attack in women can be different and can be confused with cases of anxiety or stress, they take longer to go to the emergency room and be diagnosed. Finally, during hospitalization, women often have other complications, such as heart failure, stroke, or the need for transfusions.
6. Heart disease and the most common risk factors
Finally, heart disease and its risk is another of the points that differentiate a man’s heart from a woman’s.
Men are more prone to heart attacks caused by cholesterol and being overweight. Myocardial infarction is the one that affects them the most, followed by cerebrovascular diseases, chronic ischemic heart disease, hypertension, and intra-brain hemorrhage.
Women share that same list, although they are more prone to stroke. The highest death rates are due to hypertension and diabetes, and overweight, sedentary lifestyle, and metabolic syndrome are key risk factors.
Although tobacco is the main preventable cause of coronary heart disease and affects men and women equally, in the case of women the risk increases greatly if it is combined with taking oral contraceptives.
