Top 40 amazing and interesting facts about the circulatory system

Have you ever wondered the about the big secret behind the circulatory system and how it could function so amazing wonderful and accurate.. God have created in us an amazing system Which  even scientist are yet to discover it's full secrets..
Here are the top 40 amazing facts about the circulatory system


1.
If everything was laid out end to end, arteries, capillaries, and veins, it would stretch 60,000 miles/100,000 kilometers! All of that fits inside your body.
2.
If your heart beats 80 beats per minute, 4,800 times an hour, and 115,200 times per day. That’s 42,048,000 times a year! Multiply that by 80 years of living and you’ve got 3,363,840,000 heartbeats in a lifetime. That heart definitely works hard.
3.
On average your heart will pump one to seven gallons of blood a minute. That’s as much as 2,000 gallons a day. There’s 365 days in a year so that’s 730,000 gallons of blood a year! When you’re 80 years old your heart will have pumped 58,400,000 gallons of blood.
4.
Blood is always red but our veins are blue because of light waves. Light has to go through the skin to illuminate our veins. Red and blue have different wavelengths, so they penetrate at different degrees of success. This is why our veins look blue.
5.
The blood in our bodies isn’t blue but it is different shades of red. Oxygen rich blood is bright red where as blood with less oxygen is dark red. Veins have very little oxygen so the blood they carry is dark red, where as the arteries carry oxygen rich, bright red blood. The blue is what we see, but there is no blue blood in a human body.
6.
If you’ve ever wondered how big your heart is just make a fist. That will give you an approximate size. Even though the heart isn’t very big, it’s the strongest muscle in our body. It has to be, in order to keep beating and pumping blood and nutrients to our body for our entire lives. Exercise and a healthy diet will keep your heart in great shape.
7.
A good hearty laugh where your belly hurts and tears run down your eyes is actually great for heart health. It can send 20 percent more blood flowing through your body. This is because when you laugh, the lining of your blood vessels relax and expand. Laughter also helps reduce stress. So watch a funny movie and get a good laugh for a healthy heart!
8.
The right side of the heart pumps blood to the lungs. The lungs give the blood oxygen and then is carried back to the heart. The left side of the heart pumps that now oxygen rich through the rest of your body.
9.
That thumping, beating sound you hear is caused by the valves clapping open and closed. There are four main valves in the heart, the aortic valve, pulmonary valve, mitral valve, and tricuspid valve. The heart isn’t actually beating but clapping open and closed.
10.
Signs of heart disease have been found in 3,000 year old mummies. If we should take anything from that it’s a lesson to take care of our hearts. Belly laughter, good diet, exercise, everything to keep that blood flowing strong.
11.The heart is the only muscle that works constantly and only stops after we die.
12. For every second that passes, 15 million blood cells die.
13. 200 billions of platelets, the disk-shaped fragments of blood cells, are produced on a daily basis.
14. While an adult normally has 5-6 liters of blood, an infant only has 1 liter.
15. Aorta, the largest artery of the body, supplies all the body parts with blood with the exception of lungs and the heart.
16. Oxygenated blood is carried only by the pulmonary vein, while the rest of the body's veins carry deoxygenated blood.
17. Our blood naturally has no color, and the bright red color is due to the pigment hemoglobin which is found in the red blood cells.
18. Once the blood gets through the chambers of the heart, its valves close, and the sound produced by valves is what we call ''heartbeat''.
19. The heartbeat of a woman is faster than the heartbeat of a man.
20.Another one of the fascinating facts about the circulatory system is that our hearts keep on beating even after they are removed from the body or torn to pieces.
21. It takes around 23 seconds for the blood to circulate throughout the entire human body.
22. A heart of an average adult is capable of pumping 4000 gallons of blood per day.
23. The left side of the heart is thicker than the right one, and is also stronger.
24. Our blood consists of red blood cells which are responsible for carrying oxygen, white blood cells responsible for battling diseases, platelets responsible for the clotting of blood, and a special kind of liquid called blood plasma.
25. Up to 440 gallons of blood pass through the kidney on a daily basis.
26. The lifespan of red blood cells is 4 months.
27. The only cells that don't contain nucleus in human body are red blood cells.
28. There are 30 to 40 millions of white blood cells inside human body that are responsible for protecting our bodies from foreign organisms.
29. Ten capillaries are as thick as one human hair.
30. The number of times our hearts beat per year is 30 million.
31. Red blood cells circulate throughout the body around 250 thousand times before dying inside of their birthplace, the bone marrow.
32. Out of all facts about the circulatory system, the most mind-blowing one is that its center, heart, has the power output that goes from 1 to 5 watts per minute, which equals to the power output of a 60-watt light bulb.
33. If put all of the arteries, veins, and capillaries of an adult's body end to end, the length will reach 62,500 miles.
34. The heart beats around 3 billion times in the averages person's life.
35. About 8 million blood cells die in the human body every second, and the same number are born each second.
36. Within a tiny droplet of blood, there are some 5 million red blood cells.
37. It takes about 20 seconds for a red blood cell to circle the whole body.
38. Red blood cells make approximately 250,000 round trips of the body before returning to the bone marrow, where they were born, to die.
39. Red blood cells may live for about 4 months circulating throughout the body, feeding the 60 trillion other body cells.
40. Your heart is actually made up of two separate pumps consisting of a pair of pumps, each. One set, called the atrium (or atria, if talking about one) is used to gather blood from the body and lungs. The other is used to push the blood back out to the lungs and body and is called the ventricles (or ventricle, if you are talking about one).
