About Heart

Previous Next

1. The heart is one of the most important organs in the human body, continuously pumping blood around our body through blood vessels.

2. Your heart is located in your chest and is well protected by your rib cage.

3. The heart is made up of four chambers, the left atrium, right atrium, left ventricle and right ventricle.

4. The average adult heart beats 72 times a minute; 100,000 times a day; 3,600,000 times a year; and 2.5 billion times during a lifetime.

5. Blood is actually a tissue. When the body is at rest, it takes only six seconds for the blood to go from the heart to the lungs and back, only eight seconds for it to go the brain and back, and only 16 seconds for it to reach the toes and travel all the way back to the heart.

6. A woman’s heart typically beats faster than a man’s. The heart of an average man beats approximately 70 times a minute, whereas the average woman has a heart rate of 78 beats per minute.

7. The heart pumps oxygenated blood through the aorta (the largest artery) at about 1 mile (1.6 km) per hour. By the time blood reaches the capillaries, it is moving at around 43 inches (109 cm) per hour.

8. A new born baby has about one cup of blood in circulation. An adult human has about four to five quarts which the heart pumps to all the tissues and to and from the lungs in about one minute while beating 75 times.

9. The heart begins beating at four weeks after conception and does not stop until death.

10. Five percent of blood supplies the heart, 15-20% goes to the brain and central nervous system, and 22% goes to the kidneys.

11. Although heart disease is an equal opportunity killer, symptoms of heart attack show up differently in men versus women. Whereas men often report crushing chest pain, sweating and nausea, women might instead experience shortness of breath, dizziness, light-headedness or fainting, pain in the lower chest or upper abdomen, and upper back pressure, notes the AHA.

12. If you’re a woman under 55 with moderate or severe depression, listen up. This group of women are more than twice as likely to suffer a heart attack, die of heart disease, or require an artery-opening procedure, Boling says.
