Funny and interesting information about the heart that you did not know

Aprox. 2 minutes reading time

The heart is like a pump made of muscle, which pushes blood into the body through vessels and consists of two parts, one left and one right, as well as four chambers: an atrium and a ventricle on each side. The atrium receives large vessels, which bring blood to the heart, and has special valves that open into the ventricle.

The ventricles, in turn, have valves that open into the blood vessels. The right side of the heart receives non-oxygenated blood from the body, and after it passes through the right atrium and right ventricle, the blood is pumped into the lungs. Here the blood is oxygenated and removes carbon dioxide. After passing through the lungs, the blood reaches the left atrium, then the left ventricle, from where it is pumped into the aorta, through which it is distributed throughout the body through the arteries.

Because the heart is a vital organ, it is important to keep it healthy with a well-balanced diet and exercise and to avoid things that can damage it, such as unhealthy eating, alcohol, smoking or drugs.

Although you are probably familiar with some heart-healthy tips, there is some interesting information about it that you may not know. Here are some of them:

  • A medium-sized heart is the size of a fist in an adult.
  • The heart beats about 115,000 times each day.
  • The heart pumps about 7,500 liters of blood every day.
  • An electrical system controls the rhythm of your heart. It’s called the cardiac conduction system.
  • The heart can continue to beat even when disconnected from the body.
  • The first open heart surgery took place in 1893. It was performed by Daniel Hale Williams, one of the few black cardiologists in the United States at the time.
  • The first implantable pacemaker was used in 1958. Arne Larsson, who received the pacemaker, lived longer than the surgeon who implanted it. Larsson died at the age of 86 of an unrelated heart disease.
  • The youngest person who had heart surgery was only a minute old. She had a heart defect that is fatal to most children. The operation was successful, but in the end he needed a heart transplant.
  • The oldest known case of heart disease has been identified in the remains of a 3,500-year-old Egyptian mummy.
  • The Etruscan Musarafa, an American pygmy, is the smallest mammal, but has the fastest heart rate: 1,200 per minute.
  • Whales have the largest heart of all mammals.
  • The giraffe has a lopsid heart, the left ventricle being thicker than the right. This is because the left side must go up the blood to reach the giraffe’s brain.
  • Most heart attacks occur on a Monday.
  • The human heart weighs less than a kilogram. However, a man’s heart is, on average, 70 grams heavier than a woman’s.
  • A woman’s heart beats a little faster than a man’s heart.
  • The iconic shape of the heart, as a symbol of love, is traditionally believed to come from the plant silphium, which was used as an ancient form of birth control.
  • If you were to stretch your blood vessel system, it would extend over 60,000 miles.
  • Heart cells no longer divide, so heart cancer is extremely rare.
  • Laughter is good for your heart. Reduces stress and boosts the immune system.

Your heart affects every part of your body. This also means that diet, lifestyle, and emotional well-being can affect your heart. Emotional and physical health are important for both maintaining a healthy heart.
