50 Incredible Facts About Heart

The human heart is an integral organ that circulates blood all over the body, supplying nutrients and oxygen to tissues while removing carbon dioxide and other wastes from the blood. To be active and function properly, the tissues of the body require a constant supply of nutrition which is attained by constant blood supply, and the heart does this job by pumping the blood 24×7 throughout the life of a person.

  1. Our heart rate slows down when our face touches water; this is called as mammalian dive reflex.

  33. The use of olive oil can decrease the risk of heart complications and even lowering cholesterol.
  34. A human heart pumps about 1 million barrels of blood in its lifetime, which is enough to fill more than three tankers.
  35. A heartbeat is just the sound produced by the closure of the heart valves when the blood is pushed through its chambers.
  36. A healthy heart pumps 2,000 gallons (7570 liters) of blood through 60,000 miles of blood vessels each day.
  37. The heart has its own electrical impulse that means it continues to beat even when separated from the body as long as it has an adequate supply of oxygen.
  38. The heartbeat of a fetal is twice as fast as an adult’s, which is about 150 BPM. When the fetus is 12 weeks old, its heart pumps an amazing 60 pints of blood each day.
  39. The heart pumps blood to almost all of the 75 trillion cells present in the body. Only the cornea of the eyes does not receive blood supply.
  40. The power output of the heart ranges from 1-5 watts. While the quadriceps can produce 100 watts for a few minutes, an output of one watt for 80 years is equal to 2.5 gigajoules.
