All about Human Heart
Human Heart is a part of our body’s circulatory system. It is made up of the atria, ventricles, valves, and various arteries and veins. On an average, our heart beats approximately 10,000 times in a day and it sends 2,000 gallons of blood in the entire body. The average size is equal to the fist of an adult. It weighs less than one pound. Heart cancer is extremely rare because heart cells stop getting divided. The valves of our heart open and close continuously. It is also the reason why that beating sound comes from it.
Quick Facts: –
- Human blood vessel system can be stretched out to be extended more than 60,000 miles.
- Generally, a women’s heart beats faster as compared to a man’s heart.
- When our body is at rest, blood takes only six seconds to go from the heart to the lungs and then back.
- Human heart generates pressure strong enough to squirt blood up to thirty feet across a room.
- The rhythm of our heart is controlled by an electrical system known as the cardiac conduction system.
- It has its own electrical impulse so it continues to beat for sometime even when separated from the body.
- There are total four chambers in our heart. Two upper chambers are known as the atria and two lower chambers are known as the ventricles.
- The first heart cell starts to beat as early as just 4 weeks after the conception.
